Perimeter of rectangular track = 2 (L + B)
=2( 150m + 60m)
= 2 x 210m
= 420 m
Speed of Karan = 21m/min
Time taken to finish one round = distance/ speed
= 420m / 21m/min
= 20 min
Speed of Vijay = 28m/min
Time taken to finish one round = distance/ speed
= 420m /28m/min
= 15 min
To find after how much time they will meet, we need to take lcm of their speeds
LCM of 20 and 15
20 = 2 x 2 x 5
15 = 3 x 5
LCM = 2 x 2 x 3 x 5
= 60
So they will meet each other at the starting point after 60 min that is 1 hr.
Hope you understand. Pls mark my answer as the branliest.
