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)
