Question

Select the correct answer.
Julie ran a race 2 minutes faster than Teri did. If Julie ran the race in 28 minutes, which equation can be used to find the number of minutes, m, it took Teri to run the race?
A.m+2=28
B.m-2=28
C.2m=28
D.1/2m=28

Answer 1

Answer:

B. m-2=28

Step-by-step explanation:

1. Since in the problem it says 2 minutes FASTER than 28 minutes you know you can just add 2 minutes to 28 minutes. This gets you 30 minutes.

2. Now since you know Julia ran 30 minutes you can look at the options and replace m with 30.

3. Lets try it with option A 30+2=28 that's not right. Lets try option B

30-2=28 that's right. So option B is the correct answer.
