Question

Urgent! Two people are biking towards each other. Biker A is moving at 2 m/s east, and Biker B is 10 m east of Biker A, biking towards them at 3 m/s west. How long does it take the two to pass by each other?

Answer 1

The two bikers will pass each other in 10 seconds.

Step-by-step explanation:

To find out how long it takes for the two bikers to pass each other, we need to determine the distance they need to cover together. Biker A is moving east at a speed of 2 m/s, while Biker B is moving west at a speed of 3 m/s.

The relative velocity between the two bikers is the sum of their individual velocities. In this case, it is (2 m/s + (-3 m/s)) = -1 m/s. The negative sign indicates that Biker B is moving in the opposite direction.

Now, we can calculate the time it takes for the two bikers to meet by dividing the distance between them by their relative velocity. The distance between them is 10 m, and their relative velocity is -1 m/s.

Therefore, it takes 10 m / 1 m/s = 10 seconds for the two bikers to pass each other.
