Question

The circumference of a circular track is 600 m. A moves at a speed of 30 m/sec and B at a speed of 20 m/sec. Both start from a point P on the track, simultaneously, in opposite directions. After how many seconds will they meet on the track?​

Answer 1

Answer:

1) The circumference of a circle track = 600m.

*A vehicle moves at a speed of = 30m/s.

*B vehicle moves at a speed of = 20m/s.

To Do:

1) After how many seconds will they meet on the track?

Step-by-step explanation:

1) Length of the circle track = 600m.

* A vehicle speed = 30m/s.

* B vehicle speed = 20m/s.

Find those vehicle was equally take time to cover the total distance.

Answer 2

A and B will meet after 12 s

Given,

speed of A = 30 m/s

speed of B = 20 m/s

length of track = circumference = 600m

A and B move in the opposite direction

To Find,

The time taken for A and B to meet on the track

Solution,

Let the runners meet after t second

We know distance = speed * time

then 30t = 600 - 20t

50t = 600

t = 12

A and B will meet after 12 s
