Answer 2

Given :

• A train takes 9 s to cross a pole. If the speed of the train is 48 km/h.

ㅤㅤ

Find :

• What is the length of the train.

ㅤㅤ

Using formula :

★ Length of the train = (Speed of train × Time taken to cross the pole)/One hour.

ㅤㅤ

Know terms :

• 48 km/hr → 48000 m.
• 60 minutes → 3600 sec.

ㅤㅤ

Calculations :

→ Length of the train = 48000 × 9/3600

→ Length of the train = 432000/3600

→ Length of the train = 120 m

ㅤㅤ

Therefore, 120 m is the total length of the train.
