Question

if an object falls to the ground from the top of a 100 - foot - tall building at an average speed of 10 feet per second, how long does it take to fall?

Explanation:

Step1: Recall speed - distance - time formula

We know that $time=\frac{distance}{speed}$.

Step2: Identify distance and speed values

The distance is 1000 feet and the speed is 100 feet per second.

Step3: Calculate the time

$time=\frac{1000}{100}=10$ seconds.

Answer:

10 seconds
