Alla [95]

Answer:

9240 feet

Step-by-step explanation:

Petrov ran 7 laps around a track.Each lap around the track is a distance of 1/4 mile.

Step 1

The total distance Petrov ran in miles is calculated as:

1 lap = 1/4 mile

7 laps = x mile

Cross Multiply

x = 7 × 1/4 mile

x = 1.75 miles

Step 2

What is the total distance Petrov ran in feet?

1 mile = 5280 feet

1.75 miles = x

Cross Multiply

x = 1.75 × 5280 feet

x = 9240 feet

Therefore, the total distance Petrov ran in feet is 9240 feet

Inez and Joe worked at store that sells cell phones.Inez worked for 7 hrs and 23 minutes and Joel worked for 4 hrs and 51 minute
Paul [167]

Answer:

Inez worked for 2 hours 32 minutes more than Joe

Step-by-step explanation:

Here, we are to calculate the difference in the amount of time in which both of them spent working.

Mathematically, that would be the time spent by Inez minus the time spent by Joe

= 7 hrs 23 minutes - 4 hrs 51 minutes

This works like normal arithmetic subtraction;

Since we cannot subtract 51 minutes from 23 minutes, we need to borrow 1 hour ( 60 minutes) from 7 , and it becomes 6 while our minutes become (60 + 23 = 83 minutes).

So the difference here will be (6-4)hrs and (83-51) minutes = 2 hrs 32 minutes
