​

Answer 1

Answer:

4 hrs

Explanation:

Let distance covered by bus from tri be D1

Speed = S1 = 30km/hr

Time = T1

let distance covered by bus from kochi be D2

speed = S2 = 20km/h

Time = T2

Now D1 + D2 = 200 total distance

for T1 = T2 = T

Now D = SxT

30T + 20T = 200

50T = 200

T = 200/50 = 4hrs

Both buses will meet in 4 hrs
