Mark is training for a mini triathlon. He rode his bike 3/4 mile, ran 5/6 mile, and swam 10/12 mile each day for 7 days . What combined distance did Mark exercise during the week?
Accepted Solution
A:
we know that each day rode his bike -------> 3/4 mile------> 9/12 miles (multiply by 3 both members) ran --------------------> 5/6 mile-----> 10/12 miles (multiply by 2 both members) swam ----------------------> 10/12 mile
[combined distance each day]=(9/12)+(10/12)+(10/12)----> 29/12 miles [combined distance each week]=7*29/12--------> 203/12 miles
