At the rate of 44 mph , the car will take the time 99/44 = 2 and 1/4  hours to travel 99 miles.

When we are given the speed and the distance travelled , the time taken  to travel the distance is given by distance/speed.

In this case the distance is 99 miles.

The speed is 44 miles per hour or 44 mph. (mph stands for miles per hour).

Therefore the time taken for the trip is 99/44 hours = (9*11)/(4*11)= 9/4  hours = 2 1/4 hours. Or 2 hours and 15 minutes is the time taken to travel 99 miles at the speed of 44 mph.

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.

Time taken by an object to travel a given distance id given by:

Time taken to travel = Distance travelled)/(Speed)

It is given:

Distance travelled = 99 miles

Speed = 44 mph

Substituting these values in above formula for time taken to travel:

Time taken to travel = 99/44 = 9/4 hours = 2 hours and 15 minutes.
