Answer 1

The buses meet after 200 km from the starting place.

Step-by-step explanation:

Consider the provided information.

Two buses  x and y leave same place and go in the same direction at speed of 20 km/hr and 50km/hr.

y leaves 6 hrs after x left.

The distance cover by x in 6 hours is:

$6\times20=120$

That means y needs to cover extra 120 km.

The difference of the speed of x and y is 50-20=30 km

Now divide 120 km by 30.

$T=\frac{120}{30}=4$

Hence, bus y meet with bus x after 4 hours.

The distance cover by bus y in 4 hours is:

4×50=200 km

Hence, the buses meet after 200 km from the starting place.
