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

Distance=rate times time

given
speed or rate=45mph
and time=3hr

distance=45mph times 3hr
disance=135mi

can travel 135 miles

3rd option

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.
