# 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 it takes 42 minutes to load 3.5 trucks

Let us calculate how much it takes to load 1 truck

= 42/3.5

= 12min

So, it takes 12minutes to load 1 truck.(Using the unitary method)

Now we can calculate for 6.5 trucks

Time needed = 12 min × 6.5 trucks = 78 min

Hence, it takes 78min to load 6.5 trucks.

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

**Summary:**

If it takes 42 minutes to load 3 1/2 trucks, then it takes minutes to load 6 1/2 trucks.
