Question

I don’t understand question b can somebody explain it for me?

Answer 1

9.5 minutes because if she ran 2 miles in 19 minutes you would divide them both by 2 and 19/2=9.5

Answer 2

If Gabrielle takes 19 minutes to run 2 miles then how much time does he take to complete 1 mile.

The above is the ‘b’ question.

We can get to know who long he takes to complete 1 mile taking the mean of the two in the double number line.

In this case it would be, the mean if 2 to get 1 and the mean of 19,

The mean of 2 is,

2miles / 2 = 1 mile.

And the mean of 19 mins is,

19 mins / 2 = 9.5 mins.

Hence, Gabrielle takes 9.5 mins to complete 1 mile.

Hope this helps you. Plz let me know if you have any doubts.
