plane leave jammu at 5 am and reached patna at 7.20 am flying at a speed of 600 km/h what will distance coveredby plane

lcm stands for least common multiple which can be found by taking two number and looking for the least common number they both have

m=5kg,speed=10m/s,p=m.v=1kgm

we find h.c.f in all four no. then we get h.c.f=2 then we divide all four no. by h.c.f then we get 7,9,11,13.w add together these no.

I don't understand.
