Question

Two motorcyclist A and B, started simultaneously moving towards each other. From the graph given below, find the distance each of them covered, time before they meet, and the average speed of motorcyclists.

Answer 1

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
