b) 5 times

Answer 2

Answer: a) They will meet after 72 minutes.

b) They will meet 5 times in 6 hours.

Step-by-step explanation:

Given: Ramesh takes 18 minutes to complete a round of a ground an cycle which Aslam takes 24 minutes to complete the same round.

To find the time after that they will meet, we need to find the lcm of 18 and 24

$18=2\times3\times3\\24=2\times2\times2\times3$

Thus, the lcm of 18 and 24=$2\times2\times2\times3\times3=72$

Thus, they will meet after 72 minutes.

Also 6 hours= $6\times60=360\ minutes$

The number of times they will meet in 6 hours=$\frac{360}{72}=5$

Thus, they will meet 5 times in 6 hours.
