Question

A boat is moving in a river, downstream, whose stream has speed 8 km per hour. The speed of the motor of the boat is 22 km per hour. Draw the graph of the distance covered by the boat versus hour

Answer 1

Let the boat cover distance d in time t.

To graph the straight line, we first take different values of t to obtain their corresponding values of d and then tabulate them as follows:

Now, we locate the points on the graph.

Upon joining these points, we get the required graph of the straight line.
