Ответ:
speed(v)=35kmph=9.72 m/s (approx)
time(t)=5mins
by using
v=s/t
9.72=s/5
9.72*5=s
48.6m=s
or
s= 48.6 metres
Hope it helps
Don't feel shy and say thx
Ответ:
77 m/s
Explanation:
Speed is distance divided by time. His total distance is 1000 meters. So his speed is:
s = 1000 m / 13 s
s ≈ 76.9 m/s
Rounded to two significant figures, his speed is 77 m/s.
