Question

A car is traveling at a rate of 108 kilometers per hour. What is the cars rate in meters per second? How many meters will the car travel in 20 seconds?

Answer 1

`(30meters)/(second)`

600meters

Explanation:

Use conversion factors that represent 1. You can cross cancel wods just like numbers.

`(108km)/(1hour)` ·
`(1hour)/(60 minutes)` ·
`(1minute)/(60seconds)` ·
`(1000meters)/(1 km)`

`(108000meters)/(3600seconds)`

`(30meters)/(second)`

`(30meters)/(second)` ·
`(20seconds)/(1)`

600 meters
