One lap around the West Middle School track is one-sixth of a mile. Jane ran 7 laps around the track in 10 minutes 30 seconds. What was Jane’s average speed in miles per minute?

1 mile and 1/6 of a mile

Step-by-step explanation:

the schools track was 1/6 of a mile if she had run 7 times she ran 1 whole which is 1mile and 1/6 of the mile

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
