Answer: 1,125 minutes
Step-by-step explanation:
The train is cross the tunnel at constant speed. Therefore, the speed is the ratio of the sum of the distance travelled and the total length of the train to the speed. That is to say:
[tex]t = \frac{1,125 kilometers}{60 km/h}[/tex]
[tex]t=0,01875 hours (1,125 minutes)[/tex]
Answer:
1.125 minutes
Step-by-step explanation:
The train consists of 6 carriages each of length 20 metres
Total Length of Carriages = Number of Carriage X Length Per Carriage =20 X 6
=120 metres
Gap between the carriages= 1 metre each
There are a total of 5 gaps between the carriages = 5X 1= 5m
Therefore Total Length of the train= Total Carriage Length + Total Gap Length
= 120+5= 125 metres
Total Distance Required o Cross the Tunnel= 1km + 125 metres
= 1.125km
The Speed of the Train = 60km/hr
Time Required = Distance /Speed
= 1.125/60= 0.01875 hours
We can convert the hour to minutes by multiplying by 60
0.01875 hours = 0.01875 X 60 minute = 1.125 minutes
Therefore the train requires 1.125 minutes to cross the tunnel.
