Answer:

25% or more

Step-by-step explanation:

t1 = d1/v1 , t2 = d2/v2.

d1 = d2 , and v1 = 0.8 v2

t1 / t2 = d1/d2 x v2/v1 = v2/v1 ( as d1 = d2 )

t1/t2 = v2 / v1 = v2/0.8 v2 = 1/0.8 = 1.25

Answer:

1.5

Step-by-step explanation:

so the scale factor would be equal to

12/8 and 9/6

9/6 = 1.5

12/8 =1.5

so we can conclude that the scale factor is 1.5
