Answer:
45
Step-by-step explanation:
the real distance or AB is
d = v x t = 5 x 1,8 = 9 km
then use ratio to find the real distance of BC
AB/AB' = BC /BC'
AB' = in cm
BC' = in cm
9/6 = BC/3
BC = (9 x 3)/6 = 4.5 km
so now we can. find the time needed by Finn in BC
t = d/v = 4.5/6 = 0.75 hour or ¾ hour
¾ x 60 = 45 minutes.
