Answer:
70.33 feet per second
Step-by-step 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
