Question

Julian measures the distance he drives to work each day using the odometer on his car, which measures distance in miles, accurate to the nearest tenth of a mile. His drive is in a rural area, with few stops and little traffic, so for the most part, Julian can maintain a consistent speed throughout the drive. If the odometer reads 11.7 miles, and it tak approximately 15 minutes, what is Julian's average speed on the drive? Express your answer using an appropriate level of accuracy

Answer 1

.8miles

Explanation:

Answer 2

Concept:
If we want to measure the average speed then we will need the distance covere by an object and also the time it will take to cover that distance.
Then we use the formula,

`speed=v= (distance)/(time)`
Now,in our question
Distance=d=11.7 miles
Time=t= 15 min

`speed=v= (11.7 mile)/(15 min)`
=0.78 mile/min
=0.8 mile/min
