Samantha is traveling with her family in the car. If the car is moving at an average speed of 45 miles per hour, how many miles can they travel in 3 hours? Use the formula r · t, where r represents the rate, or speed, and t represents the time.

453 miles

15 miles

135 miles

150 miles

Ok, so if you are going 45mph, then you are basically going to go 45 miles in one hour. The rate is x miles per hour. The time would be distance per x.

Therefore, 45mph represents the rate, and 3 hours represents the time.

When you take the formula r x t; in this case, it woul be 45 times 3, because you would be traveling for 3 hours, and each hour you would have traveled 45miles.

The answer you are looking for is that the family would have traveled 135 miles in 3 hours.

Distance=rate times time

given

speed or rate=45mph

and time=3hr

distance=45mph times 3hr

disance=135mi

can travel 135 miles
