Question

Ron is walking towards his house at a speed of 5 kilometres per hour and crosses a flyover in 15mins The length of the flyover​

Answer 1

Answer:

Speed of the man = 5 km/hr

$latex = 5\times \frac{1000}{60}m/min = \frac{250}{3}m/min&s=1$

Time taken to cross the bridge = 15 minutes

Length of the bridge = Speed $latex \times$ Time

$latex = \frac{250}{3}\times 15m = 1250m&s=1$

Hence option [B] is the right answer.

Answer 2

Distance = Speed × Time

Distance = 5km × 15 minutes

Distance = 75 km.
