Question

A car travels at a constant speed. What is the car's speed between checkpoints, expressed as a unit rate? Use the information given in the picture

Answer 1

44 because 1.00 -3.00 = 2.00
208miles-120miles=88.
88/2 because it is measured in kmper hour so we need one hour so it is 44

Answer 2

The constant speed is 44 miles per hour

Explanation:

We have the following details.

Point A

`t_(1)= 1.00\\x_(1)= 120`

Point B

`t_(2)= 3.00\\x_(2)= 208`

The speed in this case is defined as

`s=(\Delta x)/(\Delta t)`

Where
`\Delta x=x_(2)- x_(1)` and
`\Delta t = t_(2)- t_(1)`

Replacing all values, we have

`s=(208-120)/(3.00-1.00)=(88)/(2)=44`

Therefore, the constant speed is 44 miles per hour, which means the car travels 44 miles every hour.
