Answer 1

45

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.
