Question

Hari rides his bike from his home for 30 minutes at a fast pace. He stops to rest for 20 minutes and then continues in the same direction at a slower pace for 30 more minutes. Sketch a graph of the relationship of Hari’s distance from home over time ?

hint Hint:

Try to figure out slope of the line in different
circumstances.

The correct answer is: Slope is positive from x = 50 to x = 80, but the inclination is less.

SOL – Let distance travelled = yTime taken = x
The graph will start from origin since at time, x = 0 distance travelled, y = 0
Acc. to the question, Hari travelled on fast pace for 30 mins.
i.e., distance is increasing, and slope is positive for x = 0 to
x = 30
Then Hari stopped for 20 mins, i.e., distance remained same.
$not stretchy rightwards double arrow$ Line is parallel to x – axis
$not stretchy rightwards double arrow$ Slope of the line = 0 for x = 30 to x = 50
Further, Hari travelled on slow pace for next 30 min
i.e., distance is increasing but rate of change is less than first case since his pace is slow
$not stretchy rightwards double arrow$ Slope is positive from x = 50 to x = 80, but the inclination is less.
