Answer:
Step-by-step explanation:
When A makes 5 rounds, B makes 4 rounds.
In order to pass each other, the difference in number of rounds made by each must be one.
Here, A passes B each time. When A makes 5 rounds.
Distance covered by A in 5 rounds =5 x 400/100
= 2 km
In covering 2 km. A passes B 1 time
In covering 5 km. A passes B =5/2= 2 1_2 times.
I hope u understand
