The balloon that was farther from the town at the beginning and the one which traveled more quickly is as follows;
C. Tasha's balloon was farther from the town at the beginning but Henry's balloon traveled more quickly.
What balloon was faster?
The following is how we can determine whose balloon was faster at the beginning and the one that moved more quickly;
For Henry,
x = 0 miles
y = 15 miles
x = 2 hours, y = 31 miles
For Tasha,
y = 5x + 25
At the beginning, x = 0
Substituting 0 in the above equation gives;
y = 5(0) + 25
y = 25 miles at the start
After 2 hours;
y = 5(2) + 25
y = 35 miles
Henry's speed was 12 miles per hour while Tasha's speed was 6 miles per hour.
So, Tasha's balloon was farther from the town at the beginning but Henry's balloon traveled more quickly.
