Question

we had to drive 150 miles to the hotel we left at 1 p.m. and got there at 4 p.m. what is our average speed

Answer 1

Our average speed was 50 mph

Step-by-step explanation:

Constant Speed Motion

An object is said to travel at constant speed if the ratio of the distance traveled by the time taken is constant.

Expressed in a simple equation, we have:

`\displaystyle v=(d)/(t)`

The distance we had to drive is d=150 miles. If we left at 1 p.m. and got to the hotel at 4 p.m. This means we took t=3 hours to get there.

The average speed is:

`\displaystyle v=(150\ miles)/(3\ h)`

`v=50\ mi/h`

Our average speed was 50 mph
