Question

2.3 A and B start from the same point and run around
a circular stadium, whose circumference is 2800 m, a
the rate of 250 m and 350 m per minute respectively
in the opposite direction. They will meet each other
in?
​

Answer 1

Answer:

Let X cover ‘x’ meters while he meets Y.

Therefore,

7x=14,000 -5x

x=3500/3 m

Required time = 14/3 min.

Answer 2

Given:

A and B start from the same point and run around a circular stadium, whose circumference is 2800 m, the rate of 250 m and 350 m per minute respectively in the opposite direction.

To Find:

They will meet each other in?

Solution:

Here, we have

(x / 250) = (2800 - x) / 350

Solving this, we get

x = 1166.67

Now,

Time of meeting = 1166.67 ÷ 250 = 4.67 mins

Hence, they will meet each other after 4.67 minutes.
