Question

Aneesha travels at a rate of 50 miles per hour. Morris is traveling 3 feet per second less than Aneesha. Which is the best estimate of the speed Morris is traveling?

1 mile = 5,280 feet

Answer 1

It would be nice to know some options, but here's Morris's speed.
Since Morris is traveling at three feet per second, we want to change it to per hour.
3 * 3600 = 10800 feet per hour
And we would want to convert that to miles per hour.
10800/5280 is about 2, more specifically 2.05 ish.
So Morris is traveling 2 mph less then 50, or about 48 mph.

Answer 2

50 miles per hour is the same as 73.33 ft per second. So if Morris is traveling 3 ft per second slower than Aneesha, he is traveling 70.33 ft per second. Converting that back to miles per hour, he is traveling at a rate of 47.95 mph
