Question

A coach jogs 1.8 miles on Monday, 1.3 miles on Tuesday, and 1.2 miles on Wednesday. If the coach’s friend jogs twice as far as the coach, how many miles does the coach’s friend jog, written as a decimal?

Answer 1

So his friend runs 3.6 on m and 2.6 on t and 2.4 on w and the decimal is 0.036 and 0.026 and 0.04

Answer 2

Since it’s double,
1.8 x 2 = 3.6
1.3 x 2 = 2.6
1.2 x 2 = 2.4
3.6 + 2.6 + 2.4 = 8.6
