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.
Hi bestie lol i’m failing math too and use this app as a lil cheat :)

x² = 2x - 1
What ? What ?
Did you write the first two answers in pencil ?
They're correct ! Just do the other two exactly the same way.
-- Do the division problem printed in the "Distance ..." column.
-- Multiply the answer by 0.1 .
-- Write the new answer in the last column.
