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.
The second answer is right
To solve problem 1 what you need to do is figure out how many miles the girls have walked so far and then subtract that from the total distance they must complete.
3/4-(3/10+1/4)
Step 1:Change the denominators so that way they are all the same
3/4=15/20
3/10=6/20 15/20-(6/20+5/20)
1/4=5/20
Step 2: Begin solving the problem
6/20+5/20=11/20
15/20-11/20=4/20
Step 3: Simplify your answer
4/20=1/5
Step 4 (is optional): Write your answer in a complete statement
The three girls walk 1/5mile together to school
