Question

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)

Answer 1

The speed of the car in centimeters per second based on the information given would be 2,145.8

Answer 2

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 $\frac{miles}{hour}$

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= $\frac{1}{0.39}$ centimeter

So, 63360inches (or 1 mile)= $\frac{63360}{0.39}$ centimeter

1mile or 63360inches=162461.54centimeter

1mile=162461.54 centimeter

We have, 48 $\frac{miles}{hour}$

We have, 48 *$\frac{162461.54 centimeter}{60minutes}$

We have, 48* $\frac{162461.54 centimeter}{60*60seconds}$

So,  We have, 48* $\frac{162461.54 centimeter}{3600seconds}$

=48*$\frac{162461.54}{3600}$$\frac{centimeters}{second}$

=48*45.13$\frac{centimeters}{second}$

=2166.15$\frac{centimeters}{second}$

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