laps per minute.

Answer 1

Tanya's average speed was
`(1)/(2)` laps per minutes.

Explanation:

Tanya walked 15 laps on an indoor track in 30 minutes.

Therefore, the average speed of Tanya is
`(15)/(30) = (1)/(2)` laps per minutes.

Calculation:

The average speed formula is given by
`V = \frac{\textrm {Distance covered}}{\textrm {Number of munutes spent}}`

The distance is 15 laps.

The time is 30 minutes.

Therefore,
`V = (15)/(30)` laps per minute.

After simplification,
`V = (1)/(2)` laps per mins.

Therefore, Tanya's average speed was
`(1)/(2)` laps per minute. (Answer)
