Correct Answer - Option 1 : 175 m
Given
After their first meeting, A has runs = 50 m
B has runs = 75 m
Formula Used
Distance = Speed × Time
Calculation
First time, they run for half of the circumference of circular track
2nd time meet, they cover full circumference of circular track
First time, A runs = 50 m
In second time A runs = 2 × 50 = 100 m
When they cover full circumference A runs 100 m and B runs = 75 m
So, total circumference of circular track = 100 + 75 = 175 m
∴ The required answer is 175 m
