(ii) At rest the rate of flow of blood to the heart muscle is 0.9 cm3 g–1 per minute.
Calculate the volume of blood 1g of heart muscle would receive in 5 minutes of
vigorous exercise.

I've highlighted the important bits of that question to help you work it out in conjunction with your table of values. Does this give you a good clue?

Do you multiply by 4 then multiply by 5 to get 18?

Yes, exactly. The flow at 'vigorous exercise' is four times that of the flow at rest. So it's 0.9cm3.g-1.min-1 x 4 x 5 mins = 18cm3
