Step-by-step explanation:
The average speed is distance over time.
34 mi / 0.5 hr = 68 mph
Therefore, the driver must have been speeding at some point between the two toll booths.
Answer:
b = 7
4b - 4 = 3b + 3
4b - 3b = 3 + 4
They have two sets of equal answers...
-2 * 2 * 4 = -16
0 - 4 * -2 * -2 = -16
0 * -2 * -2 * 4 = 0
0 * 4 * 4 = 0
