Question

A train travelling at 44 Km/hr crosses a man walking with a speed of 8 Km/hr, in the same direction, in 15 seconds. If the train crosses a woman coming from the opposite in 10 seconds, then what is the speed (in km/h) of the woman? Select one: a. 10.5 Km/hr O b. 8.5 Km/hr O c. 9 Km/hr O d. 10 Km/hr​

Answer 1

Answer:

d. 10 km/hr

Step-by-step explanation:

Speed of the train = 44 km/h & Speed of the man = 8 km/h

⇒ Length of the train = (44 – 8) × (5/18) × 15 = 150 meters

Let the speed of the woman be x km/h

According to the question

⇒ (44 + x) × 5/18 = 150/10

⇒ (44 + x) = 54

⇒ x = 10 km/h

Answer 2

Answer:

one interesting question

Speed of the train = 44 km/h & Speed of the man = 8 km/h

⇒ Length of the train = (44 – 8) × (5/18) × 15 = 150 meters

Let the speed of the woman be x km/h

According to the question

⇒ (44 + x) × 5/18 = 150/10

⇒ (44 + x) = 54

⇒ x = 10 km/h
