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.
