Question

A car travels 40 miles per gallon of petrol. How many kilometres can it travel on 5 gallons of petrol? (From a KS2 CGP SATs question book). The solution in the book says 40/5 = 8
8x8=64
64x 5 = 320Km
I get the 64x5 =320Km, but not the first bit. Can anyone help please?

Answer 1

5 miles = 8Km - got it now - so no need to respond!
