6.6 hours total
bus=x hours
train=x+1.1
bicycle=6.6-2x-1.1=5.5-2x
Distance is 14(5.5-2x)+42x+105(x+1.1)=371
77-28x+42x+105x+115.5=371
119x+192.5=371
119x=178.5
x=1.5 hours on the bus or 63 miles
x+1.1=2.6 hours on the train or 273 miles
2.5 hours left for the bicycle or 35 miles
They add to 371 miles

SPEED TIME DISTANCE BIKE 14 BUS 42 y TRAIN 105 y+1.1 Total Travel 6.6 371

The time on bike can be found from the total time and the other two time expressions. Bike time, .

Missing distance expressions can be filled-in:

SPEED TIME DISTANCE BIKE 14 5.5-2y 14(5.5-2y) BUS 42 y 42y TRAIN 105 y+1.1 105(y+1.1) Total Travel 6.6 371

Solve this equation in the one variable, y, the time while riding on the bus:
