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

Solution:

Given that 42 minutes are required to load 3 1/2 trucks.

Let ‘x minutes’ be the time to load 6 1/2 trucks.

3 ½ trucks → 42 minutes

6 ½ trucks → x

By cross multiplication

3 ½ × x = 6 ½ × 42

x = (6 ½ × 42)/ 3 ½

= (13/2× 42)/ 7/2

x = 78

Thus x = 78 minutes


If it takes 42 minutes to load 3½ trucks how many minutes will it take to load 6½ trucks?

Summary:

If it takes 42 minutes to load 3 ½ trucks it takes 78 minutes to load 6 ½ trucks.
