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

Answer:

The answer is 58.18 $\frac{miles}{hours}$

Step-by-step 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:

$speed=\frac{distance}{time}$

So, we have:

distance=640 miles

time= 11 hours

$speed=\frac{640}{11}=58.18\frac{miles}{hours}$

Finally, the average rate of the car is $58.18\frac{miles}{hours}$
