Question 952874: While riding her bike to the ocean and back home 6 times, Kimberly timed herself at 49 min, 54 min, 47 min, 51 min, 67 min, and 59 min. She had set a goal of averaging 55 minutes for her rides. How many minutes will she need to spend on her seventh ride to attain her goal? Answer by macston(5194) (Show Source):
You can put this solution on YOUR website! The sum of times to average 55 minutes for 7 rides is 7(55 min)=385 min.
The sum for the first 6 rides is 327 min, so she must complete the final ride in 385 min-327 min = 58 minutes.
