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>
