14 minutes and 10 seconds.
yes 60 Seconds/minute * 15 minutes = 900 seconds. This is 10 seconds greater than 850 seconds.
To find out how long it would take for a bullet traveling at 850 meters per second to cover 1 kilometer (1000 meters), you can use the formula: time = distance / speed. Plugging in the values, time = 1000 m / 850 m/s, which equals approximately 1.18 seconds. Therefore, it would take about 1.18 seconds for the bullet to travel 1 kilometer.
850/50 = 17 hours
Too long!
I'll let you figure it out. Multiply 850 by 60. Multiply that by 60. Sorry but you should already know how to do that. This should have said divide by, not multiply by! There are 3600 seconds in an hour. A speed of 850 miles per hour is 850/3600 miles per seconds = 0.23611 miles per second, which is just slightly less than one quarter mile per second.
850 ft long
To totally cross the bridge the train must travel (850m + 150m) 1 km. 1 km in 100 seconds is 10 m/s roughly 20 mph, so the answer is yes, with ease.
