8.3

Step-by-step explanation:

2(l+w) = 40

l+w = 20

l = 2w-5

2w-5+w = 20

3w = 25

w = 25/3 = 8.3

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time
