Question

Lorenzo runs every day after school. His goal is to run 10 miles in 5 days. On Monday he ran 2.3 miles, on Tuesday he ran 2.25 miles, on Wednesday he ran 1.5 miles, and on Thursday he ran 1.755 miles. How many miles will he have to run on Friday to meet his goal of running exactly 10 miles?

Answer 1

Answer: 2.195 miles

Explanation:

Add up the miles he has already run;

= 2.3 + 2.25 + 1.5 + 1.755

= ‭7.805‬ miles

To run exactly 10 miles for the week, on Friday he needs to run;

= 10 - ‭7.805‬

= 2.195 miles
