Question

on a recent hike through riverbend park antoinette traveled 2/3 mile in 1/3 hour . Which unit rate describes antoinettes speed in miles per hour

Answer 1

Her speed is of 2 miles per hour.

Explanation:

Velocity:

The velocity is given by the following formula:

`v = (d)/(t)`

In which v is the velocity, d is the distance and t is the time.

2/3 mile in 1/3 hour .

This means that
`d = (2)/(3), t = (1)/(3)`

Which unit rate describes antoinettes speed in miles per hour?

This is v. So

`v = (d)/(t) = ((2)/(3))/((1)/(3)) = (2)/(3)*(3)/(1) = 2`

Her speed is of 2 miles per hour.
