Question

A car is traveling with speed of 50 miles/hr. What
Would this speed be in meters/sec ?

Answer 1

Explanation:

every 10 mph above 60, but below 120, you save 5 seconds a mile. But between the 30-60 area, every ten saves 10 seconds a mile (if I am remembering correctly), and every 10 between 15-30 is 20 seconds.
