She walked 1 week at one-half her regular
rate for 4 hours. Write and evaluate a
numerical expression to find the total
number of miles Hailey walked last month.​

Answer 1

Answer:

Hailey walked 70 miles last month.​

Step-by-step explanation:

Consider the provided information.

Hailey walks at an average rate of 3.5 miles  per hour.

She walked 3 weeks  at her regular rate for 6 hours per week.

$3\times (6\times 3.5)=3\times 21=63$

Hence, she walk 63 miles in last 3 weeks.

She walked 1 week at one-half her regular  rate for 4 hours.

Half of her regular  rate is $3.5\div2$

Therefore, the distance covers

$1\times (3.5\div2)4=7$

The sum of distance is: 63+7=70

Hailey walked 70 miles last month.​
