Question

Maureen went on a 3 day, 50 mile biking trip. The first day she biked 14.3 miles. The second day she biked 21.1 miles. How many miles did she bike on the 3rd day

Answer 1

14.4+21.1=35.5 miles
50.00-35.5=14.5 miles the third day.

Answer 2

Explanation:

14.3 + 21.1 + x = 50

35.4 + x = 50

x = 50 - 35.4

x = 14.6 <=== she biked 14.6 miles on the 3rd day
