While riding her bike to the ocean and back home 5 times, Mandi timed herself at 58min, 54min, 65min, 52min, and 62min. She had set a goal of averaging 60 minutes for her rides. How many minutes will she need to spend on her sixth ride to attain her goal?

Respuesta :

Answer:

69 minutes.

Step-by-step explanation:

For an average of 60 minutes the total time has to be 6*60 = 360 minutes.

So the last ride must take 360 -  (58 + 54 + 65 + 52 + 62)

= 360 - 291

= 69 minutes.
