Question

A racecar is traveling at a constant speed of 120 miles per hour. How many feet does it travel in 6 seconds? Remember that 1 mile is 5280 feet.

Answer 1

1056 ft

Explanation:

We need to convert the units from miles per hour to feet per second:

recall that i mile = 5280 ft, and one hour is 3600 seconds, so we do the conversion of the 120 miles per hour speed as follows:

`120 \,(mi)/(h) = 120\,(5280\,\,ft)/(3600\,\,s) = \,176\,\,(ft)/(s)`

which means that the car cover 176 ft in one second. Therefore, in 6 seconds it will cover 6 times this:

distance = 176 * 6 = 1056 ft
