Last week Rachel power watch 2 3/5 miles per day on each of the seven days during the same week she also jobbed 5 3/4 miles per day on 4 days what was the total amount of Miles Rachel power walk and Jog last week

41.2 miles

Step-by-step explanation:

The computation of the total amount of miles rachel walk and jog last week is as follows;

Unit rate per day is

= 2 3 ÷ 5

= 13 ÷  5

= 2.6 miles

In 7 days, she walked

= 2.6 miles × 7 days

= 18.2 miles

Now for four days, the unit per day is

= 5 3 ÷ 4 × 4

= 23 ÷ 4 × 4

= 23 miles

So, the total amount of miles would be

= 18.2 miles + 23 miles

= 41.2 miles
