As S=D/T
So, Anand
21 = 420 (perimeter of park)/T
So, time = 20 minutes
Rajan,
28= 420/T
SO, T = 15
So, they will meet : At the LCM of 20 and 15
Which is = 60 minutes
Ans; They will meet after 60 minutes OR 1hour
Hope it helps

Answer:
60min or 1 hour
Step-by-step explanation:
HCF of speed of both cyclist i.e, HCF of 21 & 28 is 7m/min.
Therefore, Speed= dist / time
→ 7m/min= 2(150+60)/time
→ time = (2*210/7) min
→ time = (2*30) min
→ time = 60 min or 1 hour.←Answer.
Thank you.
