The ratio of speeds of a train and a car is 16 : 15, respectively. A bus covers a distance of 480 km in 8 hours. If the speed of the bus is 3/4th of the speed of the train, then the distance covered by the car in 6 hours is: |
450 km 480 km 360 km 540 km |
450 km |
The correct answer is Option (1) → 450 km Step 1: Find the speed of the bus Distance = 480 km, Time = 8 hours $\text{Speed of bus} = \frac{480}{8} = 60 \text{ km/h}$ Step 2: Relate bus speed to train speed $\text{Speed of bus} = \frac{3}{4} \times \text{Speed of train}$ $60 = \frac{3}{4} \times \text{Speed of train} \Rightarrow \text{Speed of train} = \frac{60 \times 4}{3} = 80 \text{ km/h}$ Step 3: Find speed of car Given speed ratio of train : car = 16 : 15 $\text{Speed of car} = \frac{15}{16} \times 80 = 75 \text{ km/h}$ Step 4: Distance covered by car in 6 hours $\text{Distance} = \text{Speed} \times \text{Time} = 75 \times 6 = 450 \text{ km}$ |
