Question

Marty went on a bike ride to the store 8 miles away. If it
took Marty 3/4 of an hour to get there and 1/2 of an hour
to get back, what was his average rate of speed (miles
per hour) for the entire trip?

Answer 1

12.8 miles per hour.

How do you calculate the average rate of speed?

• The most popular formula for calculating average speed is the distance traveled divided by the time taken.
• If you know how far something has traveled and how long it took to get there, you can calculate its average speed. Speed is calculated as follows: speed = distance * time.
• The overall distance the object covers in a given time is its average speed. A scalar value represents the average speed. It has no direction and is indicated by the magnitude.
• Average speed is a scalar quantity defined as the average distance traveled by the body in the total amount of time. It measures in m/s.

Marty's speed is =V

$\frac{3}{4} V+\frac{1}{2} V=8*2$

         $\frac{5}{4} V=16$

           $V=12.8$

The average rate of speed for the entire trip is 12.8 miles per hour.
