The speed of a train is 220% of the speed of a car. The car covers a distance of 950 km in 19 hours. How much distance will the train cover in $3\frac{1}{2}$ hours?
Answer & explanation
Correct answer: option 1
220% = \(\frac{55 }{25}\)
Ratio of speed of , Car : Train
25 : 55
Speed of car = \(\frac{950 }{19}\) = 50 km/h
ATQ ,
25R = 50 km/h
1R = \(\frac{50 }{25}\) = 2 km/h
Speed of train = 55R = 55 × 2 = 110 km/h
Distance covered by train in 3\(\frac{1 }{2}\) hour = \(\frac{7 }{2}\) × 110
= 385 km
