Answer 1

A rocket is shot off and it takes 15.5 seconds to reach a height of 1100 meters. What is its speed?

Speed is reported as distance / time, like miles per hour (mph) in a car.

so (in a perfect world):

1. distance=1100 meters
2. time=15.5 seconds

speed =1100 / 15.5 = 70.96774193548387, which rounds to 71 meters per second
