Question

Last week, Chris kept track of the distance she ran each day.

How many miles did Chris run last week

Answer 1

7.5 miles

Explanation:

if we add all the miles of Monday to Sunday will get the answer

2 + 3/2 + 1 + 8/5 + 7/5 = (2 x 10/1 x 10) + (3 x 5/2 x 5) + (1 x 10/1 x 10) + (8 x 2/5 x 2) + (7 x 2/5 x 2).

=> 20/10 + 15/10 + 10/10 + 16/10 + 14/10

=> 20 + 15 + 10 + 16 + 14/ 10

=> 75/10 miles

=> 7.5 miles
