cle take travelling at45km/hr to cross a bridge2025 m long​

Answer 1

Solution:

We have,

• Speed of motor = 45 km/hr

{ Change km into m }

• Speed of motor = 12.5 m/s
• Length of Bridge = 2025 m

Now, We have to find the time taken by motor.

We know, Distance = time × Speed

2025 = Time × 12.5

Time = 162 Seconds

Therefore, Time taken by motor is 162 seconds.
