Question

A body is moving at a constant speed of 10km/hr. Draw its speed time graph. Calculate the distance travelled by the body during the time interval at 10min to 30min, using the speed time graph

Answer 1

When speed of the object is constant then the speed time graph will be a straight line.

It is because the speed is constant so it is not changing with time and hence graph will be the same throughout the time.

Now the distance traveled by the object can be calculated by this graph just by calculating the area of the graph

Here we need to find the area between t= 10 min to t = 30 min

This graph will be a rectangle area

So we can find the distance by using the area formula

$d = 10 * (30 - 10) * \frac{1}{60}$

$d = 3.33 km$

so the distance covered will be 3.33 km

Answer 2

Answer:

So we can find the distance by using the area formula

d = 10 * (30 - 10) * \frac{1}{60}d=10∗(30−10)∗

d = 3.33 kmd=3.33km
