Question

1. a subway train travels at an average velocity of 22.3 km/hw. how long will it take for the train to undergo a displacement of 241 mw? t = 38.9 s

Explanation:

Step1: Convert velocity to m/s

$v = 22.3 \, \text{km/h} = 22.3 \times \frac{1000}{3600} \approx 6.194 \, \text{m/s}$

Step2: Calculate time using $t = \frac{d}{v}$

$t = \frac{241}{6.194} \approx 38.9 \, \text{s}$

Answer:

38.9 s
