50 × 60 (= 3000) or 50 ÷ 1000 (= 0.05 or \(\dfrac{1}{20}\)) or 50 × 60 × 60 (= 180 000) or \(\dfrac{60 \times 60}{1000}\ (= 3.6)\) or 1000 ÷ 60 ÷ 60 (= 0.27777… or \(\dfrac{5}{18}\))	M1

M1: for 50 with at least one of ÷ 1000 or × 60

\(\dfrac{60 \times 60}{1000}\ (= 3.6)\)

1000 ÷ 60 ÷ 60

M1: (dep) for a complete method

A1: for 180

(SCB1 for both conversion factors correct but applying them wrongly eg \(\dfrac{50 \times 1000}{60 \times 60}\))
