Since the zebra is running 40 miles in 1 hour, or 40 miles in 60 minutes, the zebra would run 1 mile in 1.5 minutes or in 1 minute and 30 seconds.
1 hour and 30 mins
It will take: 30/40 = 3/4 of an hour
2 hours. If the train is one mile long and going 1 mile per hour through a mile long tunnel, in one hour the train would be completely inside the tunnel, since they are the same length and the train is only going one full tunnel length(mile) per hour. It would then take another whole hour for the end of the train to leave the tunnel, bringing the train completely out of the tunnel.
It takes 12 minutes to run a mile at 5 miles an hour.
Time = Distance/Speed = 1 mile/6 miles an hour = 1/6 hour = 10 minutes.
15 minutes, because 4 miles in an hour is 1/4 hours per mile
At 30 miles per hour you are travelling at 0.5 miles a minute.Therefore it would take 2 minutes to drive 1 mile.
At 1 mile an hour, one hour. At 60 miles per hour, one minute.
In 1 hour (at two miles per hour) you would have walked two miles. Therefore, half a mile would take 15 minutes.
if you walk 4 miles an hour how long would it take you to walk a mile
15 miles per hour
About 9 mins.
