Question

While riding her bike to the ocean and back home 6 times, corinne timed herself at 58 min, 61 min, 55 min, 59 min, 56 min, and 58 min. she had set a goal of averaging 56 minutes for her rides. how many minutes will she need to spend on her seventh ride to attain her goal?

Answer 1

Hᴇʏ! Hope that I can help!
First, we need to find the mean (average) of her 6 bike rides. To do this, we need to add up all the rides and divide that number by the amount of rides (6).


`58+61+55+59+56+58=347/6=57.8333`.

Answer: She will need to ride about 58 minutes (57.83̅ to be exact)
