Question

Hiram drove 15 miles in 12 minutes. If he

continues driving at this rate, how many
miles can he drive in 4 hours?

Answer 1

Since distance equals speed times time (d = st), we have

t = d/s

where d = 120 miles and s = 15 miles per hour

t = d / s
t = 120 / 15
t = 8

It will take 8 hours to drive 120 miles at a speed of 15 miles per hour.
