Question

Michael and LeBron are going on a road trip from Cleveland to Miami. They make several stops along the way. The distance is 1,250 miles and it takes them 20 hours of driving. If you were going to find their average speed, what unit would your answer have?

Answer 1

Average speed is found by dividing the distance travelled by the time spent. So in this case the distance is in miles and the time is in hours so the unit the answer will have is miles per hour or miles/hour

Answer 2

Answer:

$\frac{miles}{hour}$

Step-by-step explanation:

The total distance traveled $= 1,250 miles$

The total time taken for driving $= 20 hr$

The average speed for their entire journey is

$\frac{D}{T} \\= \frac{1,250}{20} \frac{miles}{hour}\\= 62.5 \frac{miles}{hour}$

The unit would be $\frac{miles}{hour}$
