Question

Figure represent a cyclist riding from a to b

Answer 1

Answer:

Distance between A and B is 25 km

Step-by-step explanation:

Let V denote the average speed of cyclist v1 from A to B and v2 from B to A.

Now

Average speed = V = ( v1 + v2 ) / 2 = ( 8 + 12 ) / 2 = 20 /2 = 10 km/h

NOW

Total distance = 2x km

Total time = T

We know that

Speed = Distance / Time

Putting values we get

Distance = speed × time = 10 × 5 = 50

Thus

2x = 50

 x = 25 km

SO Distance between A and B is 25 km
