Question

A boat is moving in river down stream whose stream has speed 8km per hour. the speed of the motor of the boat is 22km per hour. draw the graph of the distance covered by the boat versus hour

Answer 1

Solution:

Speed of stream = 8 km/hour

Speed of motor of boat = 22 km /hour

As, Boat is moving along downstream

Total Speed covered while going downstream = 22 +8= 30 km/hour

It means boat covers distance of 30 km in 1 hour.

If boat is moving uniformly, then

2 hours = 2 × 30=60 km

3 hours = 3 ×30=90 km

Plotting these points on the graph,

y=number of hours

x=distance traveled

Slope= 30

The equation becomes , y=30 x,that is graph of distance covered by the boat versus hour.
