A vehicle travels 50% of its distance at 4 km/h, and the remaining 50% at 8 km/h. What is the total distance, if it travelled for a total duration of 24 hours?
A boy goes to his school at an average speed of 3 km/h, and returns back at an average speed of 5 km/h. What is the average speed for the to and fro journey?
Two trains start simultaneously. The first train moves from Mumbai to Baroda, whereas the second train moves from Baroda to Mumbai. After they meet at a point in between, they respectively take 16 hours and 4 hours to reach their destinations. What is the ratio of their speeds?
Speeds of A and B are in the ratio 3 : 1. What is the speed of A if B can cover a distance of 2 Km in 1 hour?
A train passes two persons walking in the same direction as the train. The time it takes to move past the man running at 37km/h is 17sec, whereas the time it takes to cross the other man running at 44km/h is 18sec. What is the speed of the train?
Let the speed of the train be v km/h. Length of the train calculated with the data for the first man = $(v - 37) × 17$. It should equal the length obtained from the data for the second man. So $(v - 37) × 17$ = $(v - 44) × 18$. Please note that we have not converted seconds to hours because that factor will ultimately cancel away. Solving for v we get 163km/h.
