Question

If Vincent travels 96 miles in 1.5 hours. What is his rate of speed?

Answer 1

Answer:

In the first 1/2 hour Vincent drove 60 x (1/2) = 30 miles.

In the 2nd half-hour he drove 65 x (1/2) = 32.5 miles.

For his final 33.5 miles to be completed in 1/2 hour,

his speed had to be 33.5 / (1/2) = 67 mph.
