1. Express each as a unit rate.
a) A car travelled 150 km in 3 hour. Show your work.​

Answer 1

Given:

A car traveled 150 km in 3 hour.

To find:

The unit rate.

Solution:

We have,

Distance = 150 km

Time = 3 hours.

In this case speed is the unit rate.

`Speed=(Distance)/(Time)`

Substituting the given values, we get

`Speed=\frac{150\text{ km}}{3\text{ hr}}`

`Speed=50\text{ km/h}`

Therefore, the unit rate is 50 km/h.
