Question

Sarah walks to school, 1.5 miles in 30 minutes. what is the snswer to this

Answer 1

Answer: 3 mi/h

Explanation:

Here we have to find the speed
`V` at which Sarah walks to school, knowing the distance
`d` she has walked and the time
`t` she expends.

So, in this case we can use the following equation:

`V=(d)/(t)`

Where:

`d=1.5 mi`

`t=30 min (1 h)/(60 min)=0.5 h`

Solving:

`V=(1.5 mi)/(0.5 h)`

`V=3 mi/h` This is Sarah's speed
