Answer 1

Answer:

they will toll together 360 seconds later

Step-by-step explanation:

lcm of 120 and 180

60|120,180

|2,3

lcm = 60*2*3=120*3=360 seconds later

Answer 2

Step-by-step explanation:

They both need to be toll together, so we have to take LCM of both the timings

so here that is 360s

so after 3 minutes both will toll together.

so at 12:03 they both will toll together.
