Answer: The speed of the motorboat is 70 miles per hour
Step-by-step explanation: Subtract the initial distance, 35, from the distance at any given time, then divide the remainder by the hours.
For example, at 2 hours, the distance shown on the graph is 175 miles
Subtract: 175 -35 = 140. Then divide 140/2 = 70
At 4 hours, the distance shown is 315 miles.
Subtract: 315 - 35 = 280. Then divide 280/4 = 70
70 mph is the speed.
Answer:
I believe its A.
Step-by-step explanation:
-7+(9)=2
you can do the opposite of what is given (9-7)
1 3/4 - 5/6r = 8/3
-5/6r + 7/4 = 8/3
-5/6r +7/4 - 7/4 = 8/3 -7/4
-5/6r = 11/12
(6/-5)*(-5/6r)=(6/-5)*(11/12)
=-11/10
r = -1 1/10
