Question

If a car travels 640 miles in 11 hours, what is the average rate (speed) of the car?

Answer 1

Per hour? my best guess is 58 miles
All you have to do is divide 640 by 11

Answer 2

The answer is 58.18
`(miles)/(hours)`

Explanation:

When we have to determine the speed of an object, we need two informations: total distance and total time of travel that distance. The speed is just an average of distance and time, that is:

`speed=(distance)/(time)`

So, we have:

distance=640 miles

time= 11 hours

`speed=(640)/(11)=58.18(miles)/(hours)`

Finally, the average rate of the car is
`58.18(miles)/(hours)`
