Question

A train traveling at 37 M.P.H. had its speed increased by 22 ft. per sec.

If 88 ft./sec. = 60 M.P.H., then the train is now traveling at M.P.H.

Answer 1

52 mph

Explanation:

If 88 ft/sec = 60 mph

The 22 ft/ sec is 60/4 = 15 mph

This is so because 88/22 is 4

So we simply proceed to add this to the previous speed in mph

That gives a total of 15 + 37 = 52 mph
