Question

in one day a truck delivered 48 tonnes of sand to a building site. the first three loads measured 11.25 tonnes, 12.76 tonnes, and 12.82 tonnes. How much sand was in the fourth and final load?

Answer 1

11.17 tonnes was in the fourth and final load.

Explanation:

11.25 + 12.76 + 12.82 = 36.83 > total of the first 3 loads.

x = 4th load.

36.83 + x = 48

x = 48 - 36.83

x = 11.17
