First convert minutes to seconds so 7 x 60 + 30, that will get you the total seconds and should equal 450 secs. Divide that by 4: 450 / 4, equals 112.5 seconds

Answer:

112.5 seconds

Step-by-step explanation:

Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?

You need to do convert 7 minutes in to seconds because you cannot do anything to this unless you convert it.

Remember

1 minute = 60 seconds.

So do 7 times 60.

7 × 60

Which is 420 seconds.

Now add the 30 seconds to that.

420 + 30.

Which is 450 seconds.

Now divided 450 by 4.

450 ÷ 4.

Which is 112.5 seconds per lap.
