Question

Um móvel viaja a v= 60 kmh. Qual a distancia percorrida em:

a) T= 1 hora
b) T= 2 horas
c) T= 3 horas
d) T= 4 horas

Answer 1

a) 60×1 = 60km
b) 60×2 = 120km
c) 60×3 = 180km
d) 60×4 = 240km

Answer 2

a)

 km            h 
 60              1

Vm = 60 km/h
Δt = 1 h

Vm =  Δs
         ------
           Δt

60  =  Δs
         ------
           1

60.1 = Δs
60 = Δs
Δs = 60 km


b) Δt = 2 horas

Vm = Δs
        ------
          Δt

Vm.Δt = Δs
60.2 = Δs
120 = Δs
Δs = 120 km

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
c)¨ t = 3 horas

Δs = Vm.Δt
Δs = 60.3
Δs = 180 km

*************************************
d) t = 4 horas

Δs = Vm.Δt
Δs = 60.4
Δs = 240 km

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
Resp.:

a)1h = 60 km

b)2h = 120 km

c)3h = 180 km

d)4h = 240 km
