Question

If one airplane can travel at a maximum speed of 600miles per hour and another airplane at max speed of 720 miles per hour, then how many more miles can the faster airplane travel in 12
seconds than the slower airplane?​

Answer 1

Answer:

Slower Airplane :

1 hour = 3600 seconds

          = 600 miles

3600 seconds ÷ 12 seconds = 300

600 miles ÷ 300 = 2 miles

This means that the slower airplane can travel 2 miles in 12 seconds.

Faster Airplane :

1 hour = 3600 seconds

          = 720 miles

3600 seconds ÷ 12 seconds = 300

720 miles ÷ 300 = 2.4 miles

2.4 miles - 2 miles = 0.4 miles

Therefore, the faster airplane can travel 0.4 miles more than the slower airplane, in 12 seconds.
