A cruise carries passengers from the port to a certain point upstream and brings them back to the port. It travels upstream for 1.5 hours and downstream for half an hour. However, on one occasion, after travelling 1.5 hours upstream, the ship developed a technical error, because of which its speed reduced. At the same time, the speed of the stream suddenly increased due to a thunderstorm. The ship managed to return to the port in time. What was the ratio of the % increase in the speed of the stream to the % decrease in the speed of the ship?
1.) 1 : 2
2.) 2 : 1
3.) 3 : 2
4.) 3 : 4

A cyclist left point A for point B and travelled at constant speed of 25km/h.When he coverded the distance of 8.33km,he was overtaken by a car that left point A twelve minutes after the cyclist and travelled at constant speed too.When the cyclist travelled another 30km,he encountered the car returning from B.Assume that the car did not stop at point B.Find the distance between A and B.
Ans:60.833km. Please explain how?
Three sprinters A,B and C had to sprint from points P to Q and back again (starting in that order).The time interval between the starting times of the three sprinters A,B,C were 5 seconds each.Thus C started 10 seconds after A,while B started 5 seconds after A.The three sprinters passed a certain point R,which is somewhere between P and Q,simultaneously(none of them has reached 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 first sprinter if the distance between PQ is equal to 55m.
Ans:1m/s Can someone please explain how?
