A train is 50 percent quicker than a car in terms of speed. Both start from location A at the same time and travel 75 kilometres to point B at the same time. However, when stopping at stations along the route, the train lost around 12.5 minutes. The car's top speed is:
A. 100 kmph B. 110 kmph C. 120 kmph D. 130 kmph
Explanation: Let's say the car's top speed is x kilometres per hour.The train's speed is thus 150/100 x = 3/2 x kmph.125/10 x 60 = 75/x - 75/(3/2)x,75/x - 50/x = 5/24,120 kmph = x = 25 x ,24 /5.
