Answer: it will take 5.875 hours to move the remaining blocks

Step-by-step explanation:

It takes the construction company 3/4 hours to move move 12 rocks. It means that the time it will take them to move 1 rock is

(3/4)/12 = 0.75/12 = 0.0625 hour

Since the construction company has already moved 50 of the 144 rocks that need to be moved, then the number of blocks remaining to be moved is

144 - 50 = 94 blocks

Therefore, the time it will take them to move 94 blocks is

0.0625 × 94 = 5.875 hours
