My last qn, i think i calculate wrongly leh.

it's one speed for the boy coming home, i keep getting 1.2km/h but friends get 4.8km/h.

any advice?

i took (200/1000) / (10/60) =1.2km/h

HOW GET 4.8?

800m / 10 minutes

80m / min

1 min -> 0.08km

60 min -> 4.8km

Why you put 200m?

NO? X is the cost in cents of per liters. Then he or is it she spent $y. So should be 100y/x
