Two motorcyclist A and B, started simultaneously moving towards each other. From the graph given below, find the distance each o
harina [27]

Answer:

<em>Distance covered by motorcyclist A = 700 - 300 = 400 km</em>

<em>Distance covered by motorcyclist B = 300 - 0 = 300 km</em>

<em>The time before they met went for 5 hours</em>

<em>Average speed of motorcyclist A would be: 400/5 = 80 km/hour</em>

<em>Average speed of motorcyclist B would be : 300/5 = 60 km/hour</em>

Step-by-step explanation:

<u><em>In the given question first we have to find the distance covered by each of them.</em></u>

Look at the graph. Motorcyclist A started from 700 km and met at 300 km with motorcyclist B

Thus the distance covered by motorcyclist A = 700 - 300 = 400 km

Motorcyclist B started from 0 km and met with A at point 300 km.

Thus the distance covered by motorcyclist B = 300 - 0 = 300 km

<u><em>Now we have to find the time before they meet.</em></u>

Look at the graph. Both motorcyclists met at point t=5

Thus the time before they met went for 5 hours

<u><em>Now find out the average speed of motorcyclists</em></u>

To find the average speed we require total distance and time.

Motorcyclist A covered 400 km within 5 hours

<em>Average speed of motorcyclist A would be: 400/5 = 80 km/hour</em>

<em>Average speed of motorcyclist B would be : 300/5 = 60 km/hour</em>
