<span>Sasha
drove from her house to the grocery store in 20 minutes.
Her return trip took 15 minutes. IF the store is 7 miles from here house.
Find Sasha’s average speed for her round trip in miles per hour.
=> 20 minutes + 15 minutes = 35 minutes
=> 35 minutes is the time of her travel.
=> 7 miles is the distance.
We need to solve for the average speed.
Formula = Speed = distance / time
=> 7 / 35
=> 0.2
thus, her speed is 0.2 miles per minute (.2miles/min)
