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.
⇒ [tex]\text{Unit rate per day} = 2\frac{3}{5} =\frac{13}{5} = 2.6 \text{miles}[/tex]
Total number of miles she walked in 7 days = [tex]\text{Unit rate per day} \times 7[/tex]
=[tex]2.6 \times 7 = 18.2[/tex] miles
Also, it is given that during the same week, she also jogged 5 3/4 miles per day on 4 days.
⇒ [tex]\text{Unit rate per day} = 5\frac{3}{4} =\frac{23}{4} = 5.75 \text{miles}[/tex]
Total number of miles she jogged in 4 days = [tex]\text{Unit rate per day} \times 4[/tex]
=[tex]5.75 \times 4 = 23[/tex] miles
Total number of miles Rachel power walked and jogged last week = 18.2 +23 = 41.2 miles
