two trains start from the same point simultaneously and in the same direction. the first train travels at 40k/h and the speed of the second train is 25percent more than the speed of the first train. thirty minutes later, a third train starts from the same point and in the same direction. it overtakes the second train 90minutes later than it overtook the first train. what is the speed of the first train?
a.20kph b.40kph c.60kph d.80kph

three sprinters A,B,C had to sprint from points P to Q and back again(starting in that order). the time interval between the starting points of the three sprinters A,B,C was 5 seconds each. thus, C started 10seconds after A,while B started 5seconds after A. the three sprinters passed a certain point R, which is somewhere between P and Q, simultaneously(none of them having reached point Q yet). having reached Q and reversed the direction, the third sprinter met the second one 9m short of Q and met the first sprinter 15m short of Q. find the speed of the third sprinter if the distance between PQ is equal to 55m.
a.4m/s b.3m/s c.2m/s d.1m/s (approach pls)Find the remainder when 5^80 is divided by 187 ?

dev and nishit started simultaneously from opposite points x and y on a straight road at constant speeds. when dev had covered 40% of the distance from X to Y, nishit was 4km away from dev after having crossed dev. when nishit had covered half the way, dev was 10km short of midpoint. find the ratio of time it took dev to cover the distance from x to y to the time nishit took to cover the same distance.
a. (1+rt3)/2 b.(3rt2+4)/2rt2+1

- A and B stand at distinct points of a circular race track of length 120m. They run at speeds of a m/s and b m/s respectively. They meet for the first time 16 seconds after they start the race and for the second time 40 seconds from the time they start the race. Now, if B had started in the opposite direction to the one he had originally started, they would have meet for the first time after 40 seconds. If B is quicker than A, find B's speed.
ABCD is a trapezium,in which AD and BC are parallel.If the four sides AB,BC,CD and DA are respectively 8,10,12 and 16,then find the magnitude of the sum of the squares of the the two diagonals.
A and B started from the same point on a circular track. The ratio of their speed is n:1 (n is a whole number). If 5th and 17th time they meet at the same point, what can not be the value of n?
A) 2 B) 3 C) 4 D) 6
