A 200 meter long train passes a 1 kilometer long bridge at the speed of 40 kilometers per hour. How long does the train pass the bridge?

A 200 meter long train passes a 1 kilometer long bridge at the speed of 40 kilometers per hour. How long does the train pass the bridge?

1km plus 0.2km equals 1200m divided by 40km / h

A 200 meter long train moves in a straight line at an average speed. It takes 100 seconds for the whole train to pass through the 1.8-meter bridge

(200 + 1800) / 100 = 2000 / 100 = 20m / S
A: the train speed is 20m / s

A 200 meter long train moves in a straight line at a constant speed. When the train just passes through the 1.8 kilometer long bridge, it takes 2 minutes, then the speed of the train

If it is completely passed, it is 1800 plus the train length of 200 divided by the time of 2 minutes. The result is 100 meters per minute. If converted into hours, it is 6000 meters per hour

Emergency. The train is 200m long and the bridge is 1000m long. The train passes the bridge at a uniform speed. (1) when does the train pass the bridge? (2) When the train finished at the bridge Emergency. The train is 200m long and the bridge is 1000m long. The train passes the bridge at a uniform speed. (1) when does the train pass the bridge? (2) How long does it take for the train to finish at the bridge? (3) How long does it take the train driver to cross the bridge? Note: This is a physics problem. It requires a relational formula

To give the speed of the train, 1. The time for the train to pass the bridge is calculated from the bridge on the locomotive. The total distance from the tail of the train to the bridge is (1000 + 200) M. divide this distance by the speed of the train. 2. Divide this distance by the speed (1000-200) M. divide this by the speed is the time. 3 1000m by the speed,

A train is 200m long and passes through a 1800m long railway bridge at the speed of 20m / s. how long does it take for the train to pass through the bridge?

According to the meaning of the question, s = 200m + 1800m = 2000m,
According to the formula: v = s
T de
t=s
v=2000m
20m/s=100s．
A: it takes 100s for the train to pass through the bridge
