Question

distance 400meter time 5min find the speed kmph​

Answer 1

Answer:

1.2 mintues (opprox)

Step-by-step explanation:

We are given

distance “d” = 400 m

speed “v” = 20 km/h = 5.55 m/s

We also know that,

speed = distance/time

or time = distance/speed

therefore,

time = 400/5.55 = 72.07 seconds = 1.2 minutes (approx)
