Question

Martin and Linda live 855 miles apart. At the same time, they start driving toward each other on the same road. Linda’s constant rate is 35 mph. Martin’s is 60 mph. How long will it take them to meet?

A. 6 hours
B. 7 hours
C. 8 hours
D. 9 hours

Answer 1

D

Explanation:

Answer 2

If one is at a speed of 35 mph and the other 60, sum the speeds to work with just one number:

35 + 60 = 95mph

The formula for time is:

Time = Distance / Speed
Time = 855 / 95
Time = 9h (D.)
