The speed of a car is 25% more than that of a bus. A train covers 1110 km in 18\(\frac{1}{2}\) hours. How much distance will the car cover in 2\(\frac{2}{5}\) hours if the speed of the bus is one-third the speed of the train?
Answer & explanation
Correct answer: option 1
+25% = +\(\frac{1}{4}\)
Car : Bus
Speed 5 : 4
Speed of Train = \(\frac{1110}{37/2}\) = 60 km/h
Speed of Bus = 60 × \(\frac{1}{3}\) = 20 km/h
4 Units = 20 km/h
5 Units = 25 km/h
Distance covered by Car = 25 × \(\frac{12}{5}\) = 60 km
