The speed of a car is 40% more than that of a bus. A train covers 1020 km in $8\frac{1}{2}$ hours. How much distance will the car cover in $1\frac{3}{4}$hours if the speed of the bus is half the speed of the train? |
164 km 145 km 147 km 174 km |
147 km |
Speed of train = \(\frac{1020}{8.5}\) = 120 km/h So , Speed of bus = \(\frac{120}{2}\) = 60 km/h According to question , 40% = \(\frac{2}{5}\) Ratio of speed of Bus to car is = 5 : 7 5R = 60 km/h 1R = 12 km/h 7R = 7 × 12 = 84 km/h Distance traveled by car = 84 × \(\frac{7}{4}\) = 147 km |
