Answer 1

Step-by-step explanation:

Given :-

• A circular field has a circumference of 360 km .
• three cyclist start together can cycle 48, 60 and 72 km.

To Find :-

• when will they meet again.

Solution :-

according to the question :-

48 km/day = 48/24 km/h = 2 km/h

60 km/day = 60 km/24 h

72 km/day = 72/24 km/h = 3 km/h

Time = Distance/Speed

Time for 1st cyclist = 360/2 = 180 hrs

Time for 2nd cyclist = 360/(60/24) = 144 hrs

Time for 3rd cyclist = 360/3 = 120 hrs

L.C.M of 180, 144, 120 = 720 hrs

Total Time taken in days = 720/24 = 30 days

• Hence 30 days will they meet again
