Answer 1

41.2 miles because 3/5=.6 so 2.6 x 7 = 18.2 then for the jogging 3/4 = .75 so 5.75 x 4 = 23 so 23+18.2= 41.2 

Answer 2

Answer:

41.2 miles was the total number of miles Rachel power walked and jogged last week

Step-by-step explanation:

Unit rate are defined as the rate are expressed as a quantity of 1, such as 3 feet per second or 4 miles per hour, they are called unit rates.

As per the given statement: Last week Rachel power walked 2 3/5 miles per day on each of the 7 days.

⇒ $\text{Unit rate per day} = 2\frac{3}{5} =\frac{13}{5} = 2.6 \text{miles}$

Total number of miles she walked in 7 days = $\text{Unit rate per day} \times 7$

                                                                      =$2.6 \times 7 = 18.2$ miles

Also, it is given that during the same week, she also jogged 5 3/4 miles per day on 4 days.

⇒ $\text{Unit rate per day} = 5\frac{3}{4} =\frac{23}{4} = 5.75 \text{miles}$

Total number of miles she jogged in 4 days = $\text{Unit rate per day} \times 4$

                                                                   =$5.75 \times 4 = 23$ miles

Total number of miles Rachel power walked and jogged last week = 18.2 +23 = 41.2 miles
