Answer 1

Answer:

a) 36 minutes

Step-by-step explanation:

Solution



Required number of minutes is the LCM of 18 and 12.

We have,

18=2×32 and 12=22×3

∴ LCM of 18 and 12 is 22×32=36

Hence, Ravish and Priya will meet again at the starting point after 36 minutes.

(a) 36 minutes

Step-by-step explanation:

when Priya drive 2 round of field she takes 36min

and when Harish drive 3 round he also takes 36min
