So let's start out by labeling Ethan as X
Since 85 is 1/3 of what Ethan drove, that means Ethan drove 3 times of 85.
85= (3x) -21
85 -21 = 3x
60=3x
20 = x
Answer:
the answer is 7

Given:
Carol has 88cm of string and cuts it in the ratio 5 : 6.
To find:
How much longer is the longest piece compared to the shortest piece.

Now, the lengths of pieces are:
And,
The difference between the longer piece and shorter piece is:
Therefore, the longer piece is 8 m longer than the shorter piece.
