A car is traveling at 44 mph. How long will it take to travel 99 miles?

Given the car's speed (s)= 44
mph


We need to determine the time ( t) that takes the car
to travel 99 miles.


We are given the speed ( s) and the
distance ( d). Then, we can use the distance formula to calculate the time
required.


We know that:


Speed
( mph)= distance ( mile) / time ( hour)


We will cross
multiply:


==> speed * time =
distance


Now we will divide by
speed.


==> time = distance/
speed.


Now we will substitute with given
values.


==> time = 99 / 44= 9/4 (
hour)


==> t= 2.25 ( hour) = 2:
15


Then, the time required for the car to
travel 99 miles at 44 mph speed is 2 hours and 15
minutes.
