Lin runs 8 laps around a track in 26 minutes.

How many minutes and seconds?

3 minutes and 15 seconds per lap.

Step-by-step explanation:

26 ÷ 8 = 3.25

Multiply 3.25 times 60 to get the amount in seconds.

3.25 x 60 = 195

Then, subtract 60 from 195 until you can't subtract 60 anymore.

195 - 60 = 135

135 - 60 = 75

75 - 60 = 15

Add the number of times 60 was subtracted.

60 = 1 minute

So 1 + 1 + 1= 3 minutes.

Then, the 15 left over from 195 after 60 was subtracted from it three times is the amount of seconds.

3 minutes and 15 seconds per lap.

15+25d=t

Step-by-step explanation:

the initial value is 15 it increases(+) by 25 to each kilometer(distance=d) of depth.
