Answer:
velocity = v = 15 m/s
time = t = 20 second
distance = d= ?
velocity = distance ÷ time
distance =velocity ×time
distance =d = v × t
distance = d=15 ×20
distance = d = 300 m

Answer:
300m or 0.3 km
Explanation:
as D = S * T
let x be the distance
=> x= 15m/s * 20s
=> x= 300m
=> x= 300 / 1000 [ 1km = 1000m]
=> x= 0.3km
