Question 60

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?

Solution

Speed of the car = $$\frac{950}{19}$$ = 50 km/h

Given, speed of the train is 220% of the speed of the car

$$\Rightarrow$$ Speed of the train = $$\frac{220}{100}\times50$$ = 110 km/h

$$\therefore\ $$Distance covered by the train in $$3 \frac{1}{2}$$ hours = $$110\times3\frac{1}{2}$$ = $$110\times\frac{7}{2}$$ = 385 km

Hence, the correct answer is Option B
