Answer:
Distance covered by motorcyclist A = 700 - 300 = 400 km
Distance covered by motorcyclist B = 300 - 0 = 300 km
The time before they met went for 5 hours
Average speed of motorcyclist A would be: 400/5 = 80 km/hour
Average speed of motorcyclist B would be : 300/5 = 60 km/hour
Step-by-step explanation:
In the given question first we have to find the distance covered by each of them.
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
Now we have to find the time before they meet.
Look at the graph. Both motorcyclists met at point t=5
Thus the time before they met went for 5 hours
Now find out the average speed of motorcyclists
To find the average speed we require total distance and time.
Motorcyclist A covered 400 km within 5 hours
Average speed of motorcyclist A would be: 400/5 = 80 km/hour
Average speed of motorcyclist B would be : 300/5 = 60 km/hour
