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
