A car is traveling at 48 miles per hour. What is the speed of the car in centimeters per second? (1 mile = 5,280 feet, 1 foot = 12 inches, 1 centimeter = 0.39 inch)

Solution:

We have 48
(miles)/(hour)

To convert, miles to centimeters.

Let us convert miles to feet and then inches and then centimeters.

1miles=5280feet

And, 1 foot=12inches

So, 5280 feet or 1 miles =12*5280inches

So, 1miles=63360inches

Now, Let us convert inches to centimeters

1centimeter=0.39inches

Or, 1 inch=
(1)/(0.39) centimeter

So, 63360inches (or 1 mile)=
(63360)/(0.39) centimeter

1mile or 63360inches=162461.54centimeter

1mile=162461.54 centimeter

We have, 48
(miles)/(hour)

We have, 48 *
(162461.54 centimeter)/(60minutes)

We have, 48*
(162461.54 centimeter)/(60*60seconds)

So, We have, 48*
(162461.54 centimeter)/(3600seconds)

=48*
(162461.54)/(3600)
(centimeters)/(second)

=48*45.13
(centimeters)/(second)

=2166.15
(centimeters)/(second)

Answer:= Speed of the car in centimeters per second is 2166.15 centimeters/second
