Question

1 b. Sarah roller skates with a constant speed of 16 miles per hour. How far can she travel in 150 minutes?

Answer 1

Given:

Speed, s=16 miles/hour

Time, t=150 minutes.

The objective is to find the distance d.

Let's convert the speed as miles/minute.

It is known that 1 hour=60 minutes.

`\begin{gathered} \text{speed, s=}(16)/(60) \\ s=(16)/(60)\text{ mile/minute} \end{gathered}`

Now, find the distance.

`\begin{gathered} d=s\cdot t \\ d=(16)/(60)\cdot150 \\ d=(240)/(60) \\ d=4 \end{gathered}`

Hence, the distance travelled by sarah is 4 miles.
