A) 1 km.
60 km:60 km =1 km
b) 15 km.
60:4 = 15
c) 50 km.
60 -50 =10
d) 80 km.
60:20 = 3
60 + 20 = 80
e) 165 km .
120 + 45 = 165

V = 60 km/h

a) t = 1 min = 1/60 h
s = v * t
s = 60 km/h * 1/60 h = 1 km

b) t = 15 min = 15/60 h
s = 60 km/h * 15/60 h = 15 km

c) t = 50 min = 50/60 h
s = 60 km/h * 50/60 h = 50 km

d) 1h 20 min = 80/60 h
s = 60 km/h * 80/60 h = 80 km

e) t = 2 h 45 min = 165/60 h
s = 60 km/h * 165/60 h = 165 km
