A train covers a distance of 12 km in 12 minutes. If its speed is decreased by 5 km/h, then the time taken by it to cover the distance of 22 km will be:
Answer & Solution
Correct Answer:
Option
A
Initial speed = $$\frac{{12 \times 60}}{{12}}$$ = 60 km/h
New speed = 60 - 5 = 55 km/h
Time taken to cover 22 km = $$\frac{{22 \times 60}}{{55}}$$ = 24 min
New speed = 60 - 5 = 55 km/h
Time taken to cover 22 km = $$\frac{{22 \times 60}}{{55}}$$ = 24 min
