A car travels 40 miles per gallon. Fuel costs £1.20 per litre. If £54 is spent on fuel, how many miles will that car travel on that amount?

(4.5 litres is 1 gallon)

what are the

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm

the one where 1 and 2 are directly across from each other.
