Question

if it takes 42 minutes to load 3 1/2 trucks how many minutes will it take to load 6 1/2 trucks?

Answer 1

Acc to ques, it takes 42 minutes to load 3 1/2 trucks.

That means 3.5 part of the truck can be loaded in 42 minutes.

1 part of the truck will be loaded in (42÷ 3.5) minutes.

Thus 6$\frac{1}{2}$ of the truck will be loaded in 6.5 × (42÷ 3.5) minutes.

i.e. 273 / 3.5 = 78 minutes.

It will take 78 minutes to load 6 1/2 trucks.

Answer 2

= 78 minutes.
