Question

solve this with process​

Answer 1

Step-by-step explanation:

The train is running at a speed of 42kmph. So the distance covered by train in meters per second is:

The train is running at a speed of 42kmph. So the distance covered by train in meters per second is:42*(5/18)=35/3 m/sec

The train is running at a speed of 42kmph. So the distance covered by train in meters per second is:42*(5/18)=35/3 m/secNow the time required to the train to cross a man of is the same amount of time that train will take to cross itself that is 280 m.

The train is running at a speed of 42kmph. So the distance covered by train in meters per second is:42*(5/18)=35/3 m/secNow the time required to the train to cross a man of is the same amount of time that train will take to cross itself that is 280 m.So 280*(3/35) = 24 seconds.

hope it will help you dear ☺️

Answer 2

Answer:

t = 11 .76 hours

Step-by-step explanation:

distance = 280m = 0.28 km

speed = 42 km/hr = 11.667 m/s

Time Taken = ?

speed = distance / time taken

t = 0.28 × 42

= 11 .76 hours

or

t = 280 × 11.667

= 3266. 76 seconds
