Question

Marissa can run 1 mile in 10 minutes.

How many miles can she run in a half
hour?
(If there is extra information, identify it. If
there is not enough information, tell what information is needed.

Answer 1

3 miles
Because if you notice that half an hour is 30 minutes then you multiply 1 mile and 10 minutes by 3 and you’ll get 3 miles in 30 minutes.
1mile/10minutes x 3 = 3 miles in 30 minutes

Answer 2

3 miles

Explanation:

if she can run at a constant speed for 30 minutes, then it is 3 miles. But, if there is some reason that she cannot run at the same rate as she did for one mile, the answer is unknown.
