What is conversion?

Conversion means to convert the same thing into different units.

Aneesha travels at a rate of 50 miles per hour. Morris is traveling 3 feet per second less than Aneesha.

We know that 1 mile = 5,280 feet.

Then convert the feet per second to miles per hour. Then the speed of the Morries will be

⇒ 3 feet / 1 second

⇒ (3 / 5285) miles / (1 / 3600) hour

⇒ (3 / 5285) x (3600)

⇒ 2 miles per hour

Then the best estimate of the speed Morris is traveling will be

⇒ 50 - 2

⇒ 48 miles per hour

The best estimate of the speed Morris is traveling will be 48 miles per hour.

Answer 2

48 miles per hour

3 feet / second

There are 5285 feet in a mile

60(seconds in a minute) x 60(minutes in an hour) which 60x60=3600 seconds per hour

3600x3 to find out how many feet per hour
3x3600=10,800 feet slower per hour

10,800 % 5,280 (feet in mile) = 2 mph slower

50mph - 2mph = 48mph
