Answer 2

Answer:

Given:

• The length of a train is 140m and it's speed is 72km/hr.

Find:

• How long will it take to cross. A pole 220m long.

Calculations:

• Distance = 220 + 140.
• Distance = 360.

Using formula:

• Distance/Speed × Time is equal to 1.

⇢ 1000/60

⇢ 72/1

⇢ 7200/60

⇢ 1200/1

⇢ 20/1

⇢ 360/20 × Time = 1

⇢ Time = 18

Therefore, 18 sec is the required answer.
