Question

Charmaine is participating in a 6-day cross-country biking challenge. She biked for 46,63, 54, 70, and 60 miles on the first five days. How many miles does she need to bike on the last day so that her average (mean) is 59 miles per day?

Answer 1

61 miles.

Explanation:

For to get a mean of 59 the total miles must be 6 * 59 = 354.

Total for 5 days = 46+63+54+70+60 = 293

So on te last day she must bike 354-293 = 61 miles.
