A car covers a distance of 40 km in 24 minutes. If its speed is decreased by 40 km/hr, then what will be the time taken by it to cover the same distance ?
Answer & explanation
Correct answer: option 4
According to question ,
Speed of A = \(\frac{40}{24}\) × 60 = 100 km/hr
New speed = 100 - 40 = 60 km/h
Time taken by reduced speed = \(\frac{40}{60}\) = \(\frac{2}{3}\) hr
Now , \(\frac{2}{3}\) × 60 = 40 min
