Ashraf takes 1500 steps to walk d metres from his home to the station. Each step is 90 centimetres correct to the nearest 10 cm.
Find the lower bound and the upper bound for d.

lower bound = 90 - 10 = 80 cm

upper bound = 90 + 10 = 100 cm

lower bound d = 1500 x 80 cm = 120,000 cm

upper bound d = 1500 x 100 cm = 150,000 cm
