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 traveling?

Answer 1

70.33 feet per second

Explanation:

Since, speed of Morris is given is feet per second

lets, convert Aneesha's speed in feet per second.

We know that

1 mile = 5280 feet

1 hour = 60 minutes

1 minute = 60 seconds

thus,

1 hour = 60*60 seconds = 3600 seconds

Now

Aneesha's Speed = 50 miles per hour

to convert miles per hour into feet per second

we will use 1 miles = 5280 feet

1 hour 3600 second

Aneesha's Speed in feet per second = 50*5280 feet/3600 seconds

Aneesha's Speed in feet per second = 73.33 feet per seconds

Given that

Morris is traveling 3 feet per second less than Aneesha

Morris speed = Aneesha's Speed in feet per second - 3 feet per second

Morris speed = (73.33 - 3 ) = 70.33 feet per second

Thus, morris speed is 70.33 feet per second
