Answer:

A and B will be again at the starting point, after 12 minutes.

Step-by-step explanation:

The difference between A and B's speeds can be used to determine their relative speeds:

$Relative \: speed = 225 m/min - 150 m/min$

= 75 m/min

This indicates that B is closing the gap on A by 75 metres per minute.

We can utilise the idea of relative speed and the distance formula to determine how long it will take them to return to the beginning point:

Distance is determined by multiplying time and speed.

$Distance = Speed \times Time$

Since they are moving in a 900 m circle, the distance between them may be calculated as the circle's diameter, which is 900 m as well.

Thus, We can write:

Relative Distance = 900 m

Relative Speed = 75 m/min

$Time = \frac{Distance }{ Speed}$

$Time = \frac{900 m }{ 75 m/min}$

Time = 12 minutes

Therefore, after 12 minutes, A and B will be again at the starting point.
