Danielle is traveling and siri tells her to go 35 miles north and make a u-turn. after Danielle makes the u-turn, Siri tells her to travel 17 moles South. It took Danielle 1 hour to do this. What speed is Danielle traveling (in MPH)?

Respuesta :

We are asked to determine the speed of a person. The average speed is defined as the distance over time. Therefore, the speed is:

[tex]v=\frac{d}{t}[/tex]

Where "d" is the distance and "t" is time. Replacing the values:

[tex]v=\frac{35miles+17miles}{1hour}[/tex]

Solving the operations:

[tex]v=52mph[/tex]

Therefore, the speed is 52 miles per hour.
