Fill in the blanks to complete the steps of this word problem: Moby can use his jetpack to travel 240 miles in 4 hours. How far can he travel in 10 hours? If d represents the distance Moby travels, one way to write a proportion for this situation is BLANK /4=d/ BLANK.
Using cross multiplication gives us a new equation: BLANK = 4d.
The final step is to divide by BLANK, which tells us that Moby can travel BLANK miles in 10 hours.
