1200 divided by h times s
How many hours are needed to travel 163 km by train?
Obviously the answer depends on the number of stops and the speed of the train. Assuming there are no stops and the the trains run at 70 mph, the answer is about an hour and a half.
A train is running 3 minutes late and losing 3 seconds per minute .How many more minutes will it take for the train to be running an hour late?
1140 minutes [I solve the problem in hours and convert to minutes at the end, just to make the numbers smaller.] 3 seconds per minute=3 minutes per hour So the lateness of the train (in minutes) is given by: Minutes late=3+3t, where t is the time in hours. We want to find the point where the train is 60 minutes (which equals one hour) late: 60=3+3t 60-3=3t 57=3t t=57/3=19 So in 19 hours (=19*60=1140 minutes), the train will be 60 minutes, or one hour, late.
If a train is running 4 minutes late and losing 4 seconds per minute how many more minutes will it take for the train to be running half an hour late?
The train is running 4 minutes late. It "needs" to be running 1/2 hours, or 30 minutes late. So it needs to lose 26 minutes, or 26*60 = 1560 seconds. It loses 4 seconds per minute. So it loses 1560 seconds in 1560/4 = 390 minutes = 61/2 hours.
