Question

Andrea has a goal of running at least 50 miles this month. She has already run 7 miles. How many miles does Andrea need to run each day to meet her goal if there are 25 days left in the month

Answer 1

At least 1.72 miles per day.

Explanation:

Given: Goal of running is at least 50 miles in a month.

Andrea have already run 7 miles.

Days left in the month is 25.

As given, Andrea have already run 7 miles.

∴ Andrea need to run this month=
`50\ miles - 7\ miles= 43\ miles`

Days remaining this month is 25.

Now, finding miles need to run each day to meet her goal.

Miles need to run each day=
`(remaining\ miles)/(remaining\ days)`

⇒ Miles need to run each day=
`(43)/(25) = 1.72\ miles`

∴ Andrea need to run at least 1.72 miles to meet her goal this month.
