Sarah walks to school, 1.5 miles in 30 minutes. what is the snswer to this
nevsk [136]

Answer: 3 mi/h

Step-by-step 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=\frac{d}{t}

Where:

d=1.5 mi

t=30 min \frac{1 h}{60 min}=0.5 h

Solving:

V=\frac{1.5 mi}{0.5 h}

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