# Time Speed Distance - Questions & DiscussionsQuantitative Report

So, there are two trains on parallel tracks facing opposite directions. The starting and ending points of the trains form a rectangle 5m x 150m. Two men standing at the tail end of each train start moving towards each other along the line of the train at the same time when the trains start moving...

At how many points between 10 O'clock and 11 O'clock are the minute hand and hour hand of a clock at an angle of 30 degrees to each other? (1) 2 (2) 4 (3) 1 (4) 3 ans-btwn any hr all the angle r repeated 2 times...xcept 180 and 0...hence the ans is two..
How often between 11 O'clock and 12 O'clock are the hands of the clock together at an integral number value?(1) 55(2) 56(3) 4(4) 5 ans-there are 4 integral values btwn 11 to 12...i.e 56 57 58 59...so hr hand can take only these 4 value btwn 11 to 12...hence both the hands will be toghter on int...

@chandrakant.k Its speed(velocity)...............can u plz explain its solution
@Rshmi05 is it 6.1??? P.S : last part of the question is not clear. what is V here?? or is it a typo?
plz solve dis one..................... A pedestrian left point A for a walk , going with the speed of 5 km/h .When the pedestrian was at a distance of 6 km from A, a cyclist followed him ,starting from A and cycling at a speed 9 km/h higher than that of of the pedestrian .When the cyclist o...
@fungus How can we solve it under 2 minutes ?
is it 66.68 sec
Arjun and Bheem are standing at point A on a circular track with circumference 300 m. Cherry is standing at point B which is diametrically opposite point A on the track. All three of them start running simultaneously on the track; Arjun and Cherry run in clockwise direction at 3 m/s and 4 m/s res...
okk.. well i used a more faster approach...but for u....for the purpose of understanding it can be done like this what is common thing which is equal for both cars???.......- the distance traveled from starting point so for second car the distance = v(2) *T = 100kmph* Tfor first car the dist...

yes ...but how ..i am getting 520 km..plz explain
. One car sets off at 8:00 a.m. at 60kmph, at 11:00 a.m. another car starts at 100kmph. At what distance from the starting point both will meet.

zeeshannasim 270 km from start point if going in same direction. 29 May.
The distance travelled by Ben in 648 sec is travelled by the bullet in 12 sec
Hence ratio of speeds of bullet & Ben is
648/12=330/x
x=55/9 m/s
or 22km/hr
22 km/hr
A question 4 u guys-Kiran fires a gun at 10:30 a.m. when ben starts on his car towards kiran. kiran fires a second time at 10:41 a.m. but ben hears the second shot ten minutes 48 sec after hearing the first sho. what was ben's speed if speed of sound in air is 330 m/s?
zeeshannasim ans is 55/9 m/s..... 29 May.
zeeshannasim solution is as :- Speed of Ben/Speed of Sound = Time of S.... 29 May.

Cost is proportional to rate ratio*seating capacity ratio*speed ratio
Hence 3*5*7/2*2*4
=105/16

Speed of Rajesh = 1 steps/minSpeed of Sunil = 2 steps/min
Speed of escalator = a steps/min
40 + 40*a = 2*40 - 40a
=> 80a = 40
=> a = (1/2) steps/min
Total steps = 60
Rajesh traveled = 40 steps
Sunil must have traveles = 20 steps
=> Difference = 20 steps
is the answer 20..??if yes then i will explain my appraoch..
2 cars involved,rate ratio is Rs3:Rs2 per km.,seating capacity ratio=5:2,speed ratio=7:4.find ratio of max.cost incurred given dat no wastage of tym or capacity.
ans:105:16

hi,
Can anyone help me in solving Escalators questions??
what is the logic behind in analysing relativity in escalators questions , up/down both..
for example i am posting one question: Pls help me out:
Rajesh Walked down a descending escalator and took 40 steps to reach the bottom. S...
dude i got the answer. it will be 4 only..
look a will cross c each time he 750 m ahead of c...ok?
so at 2000 m dey will be equal..at 4000..a will be 500 m ahead...at 6000 a will be 1000 m ahead..ie..he crosses once..at 8000..he will 250+500=750 m ahead again so 2nd tym..then at 12k dey ...
Amul and Cadbury run a 12km race around a circular track of circumference 750m. Amul can beat cadbury in a race of 2000 m by 500 m. If amul gives a headstart to cadbury by 500m then how many times amul overtake cadbury in the race?
ans is 4

coul du explain y the gaps are considered here
ya that could be correct coz even i got 0.1 as ans. hw did u get 2 solutions
My ans is 0.1 km/min.
m getting 6km/hr or .1km/min...
if the ans is correct i'll post the solution...
Hi puys, I am not being able to understand how to solve the following question:
