One lap around a track is 1/4 of a mile. It takes Seth 1/30 of a hour to run one lap. What is Seth's unit rate per hour around the track?

Seth's unit rate per hour around the track is 7.5 miles per hour.

Step-by-step explanation:

Step 1:

First, we convert the given fractions into decimals.

of a mile = 0.25 of a mile = 0.25 miles.

Seth takes of an hour to run a lap.

To determine how many minutes it took Seth, we multiply the given fraction with the number of minutes in an hour i.e. 60 minutes.

of an hour minutes.

So it takes Seth 2 minutes to run a lap.

Step 2:

To determine Seth's unit rate per hour, we need to determine the distance that Seth runs in an hour at the same rate.

If he covers 0.25 miles in 2 minutes then we multiply that value by 30 to get the distance covered in an hour.

If 0.25 miles is covered in 2 minutes, then the distance covered in 1 hour miles.

So Seth's unit rate per hour around the track is 7.5 miles per hour.

answer: check all that apply, where the options?

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
