A car moving at a speed of 75 km/hr covers certain distance in 2 hours. If its speed is reduced by 15 km/hr, in what time it will cover the same distance?
Answer & explanation
Correct answer: option 2
Total distance covered - 75 x 2 = 150 km
After reduction of speed:
Time = \(\frac{Distance }{Speed }\)
Time = \(\frac{150 }{60 }\)
Time = 2.5 hours or 150 min
