A train departs at 9:15 a.m. and arrives at 1:45 p.m. How long is the journey?
4 hours 30 minutes
Converting the arrival time to the 24-hour format, 1:45 p.m. becomes 13:45.
The departure time is 9:15 a.m., which is 09:15 in the 24-hour format.
The duration of the journey is \(13{:}45 - 09{:}15 = 4\ \text{hours}\ 30\ \text{minutes}\).
Hence, the journey lasts 4 hours 30 minutes.
Important Questions from Speed Time and Distance
A train travelling at a speed of 72 km/hr crosses a post in 20 seconds. If it crosses another train travelling at a speed of 54 km/hr in the same direction in 1 minute 45 seconds, then the difference in length between the two trains is
Rajiv's boat can travel along the current at the 8 km/hour and against the current at the rate 6 km/hour. Find the time taken by the boat to sail 28 km in still water.
