Question

Sonia travels 500 km to her home by train and bus she takes 5 hours if she travels 100 km by train and remaining by bus . if she travels 120 km by train and remaining by bus she takes 30 minutes longer find the speed of train and bus

Answer 1

Answer:

The sped of train is 33.33 km/h

The speed of bus is 200 km/h

Step-by-step explanation:

time=distance / speed

Let speed of V1 and speed of bus be V2..

100/V1 + 400/V2=5   _ (1)

120/V1 + 380/V2=11/2 _(2)

Multiplying (1) by 12 and (2) by 10

1200/V1 + 4800/V2=60

-1200/V1 - 3800/V=-55

1000/V2=5

Therefore, V2=200 km/h

Substituting the value of V2 in (1);

V1=100/3=33.33 km/h
