To find the amount of paint needed to paint 100 km of road, we can set up a proportion based on the information given:
180 litres of paint is needed to paint 6 km of road.
Let x be the amount of paint needed to paint 100 km of road.
180/6 = x/100
Cross multiply to solve for x:
6x = 180 * 100
6x = 18,000
x = 18,000 / 6
x = 3,000
It will take 3,000 litres of paint to paint 100 km of road.
The machine that paints white lines on roads uses 180 litres of paint to paint 6 kilometres of road , how many litres will it take to paint 100km of road
