Question 1095832: While riding her bike to the ocean and back home 7 times, Mary timed herself at 52min, 62min, 51min, 50min, 48min,68min, and 65min. She had set a goal of averaging 56 minutes for her rides. How many minutes will she need to spend on her eighth ride to attain her goal? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! average=total/n
56=total/8
total=448 minutes
The first seven rides add to 396
The eighth ride needs to be 448-396=52 minutes.
