The speed of the boat is 50 miles per hour.
We have given that,
The graph shows the distance, y, in miles, of a moving motorboat from an island for a certain amount of time, x, in hours
A graph titled Distance Vs Time is shown with Time in hours labeled on the x-axis and Distance from Island in miles labeled on the y-axis. The scale on the x-axis shows the numbers 1, 2, 3, 4, 5, 6, 7, and the scale on the y-axis shows the numbers 0, 25, 50, 75, 100, 125, 150, 175, 200, 225. The graph shows a straight line joining the ordered pairs 0, 25, and 1, 75, and 2, 125, and 3, 175, and 4,225.
We have to determine the speed of the motorboat.
What is the speed?
The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time it is thus a scalar quantity.
The graph is showing for every 1 hour the boat is 50 miles further away
1hour=50 miles from the graph
So the speed of the boat is 50 miles per hour.
