Answer 1

Respuesta:

Explicación:

1)

d= 100 m

t = 8 seg

v = d/t = 100 m/8seg = 12.5 m/s

2)

t = 9 h

v=?

d = 890 km

v = d/t = 890 km/9h = 98.88 km/h

3)

d=?

v = 125 km/h

t = 2.30 min = 0.03833 h

d =v x t

d = 125 km/h x 0.03833 h

d = 4.79 km

4)

d= 800 m

t = 180 seg

v=?

v = d/t = 800 m/180 seg = 4.44 m/s
