Question

Problem Page A car is traveling at a rate of 63 miles per hour. What is the car's rate in feet per second? How many feet will the car travel in 15 seconds? In your computations, use the fact that 1 mile is equal to 5280 feet. Do not round your answers.

Answer 1

Providing 1 mile is 5280 feet, then,

$v=63 miles/s=63\times5280 feet/s=332640\ \ \ \ feet/s$

It will travel,

$space=v\cdot t=332640\cdot 15/3600=1386\ \ \ feet$

in 15 seconds.
