Answer:

780 km was traveled by train

420 km was traveled by bus

Explanations:

Total distance traveled = 1200 km

Distance traveled by bus = x km

Distance traveled by train = y km

(Distance traveled by bus) + (Distance traveled by train) = Total distance

x + y = 1200..........(1)

They ride on the train 360 more kilometers than the bus

y = x + 360..........(2)

Substitute equation (2) into equation (1)

x + (x + 360) = 1200

2x + 360 = 1200

2x = 1200 - 360

2x = 840

x = 840/2

x = 420

Substitute the value of x into equation (2)

y = 420 + 360

y = 780

780 km was traveled by train

420 km was traveled by bus
