A woman on vacation travels first 150 km at 60 km/hr and the next 150 km at 25 km/hr. The average speed for the first 200 km of the tour is:

2 trains running in oppsite directions cross a stationary lady standing at a point named F in 26 seconds and 21 seconds respectively. Further, the 2 trains cross each other in 24 seconds. Determine the ratio of the speed of the 2 trains?

The ratio between the speeds of two train is 2 : 5. If the first train runs 350 km in 5 hours, then the difference between the speeds (in kmph) of both the trains is:

A man can walk uphill at the rate of $2\frac{1}{2}$ $km/hr$ and down hill at the rate of $3\frac{1}{2}$ $km/hr$. If the total time required to walk a certain distance up the hill and return to the starting point is 4 hr. 36 min, then what is the distance walked up the hill by the man?
