A car travels at a speed of 60 miles per hour. If it travels for t hours, write an equation to find the distance traveled.

• distance = 60t

• distance = 60t^2

• distance = 60 + t

• distance = 60/t

Liam has $50. He spends $x on a video game. Write an equation to find out how much money he has left after the purchase.

• 50 - x

• 50 + x

• 50 - 10

A garden has a length of 10 feet and a width of w feet. Write an equation to find the area of the garden in square feet.

• Area = 10w

• Area = 10 - w

• Area = 10 + w

• Area = w^2

If a book costs $15 and you have a budget of b dollars, write an equation to determine how many books you can buy.

• number of books = b * 15

• number of books = b / 15

• number of books = 15 - b

• number of books = b + 15

A swimming pool is filled with water at a rate of 5 gallons per minute. If it takes t minutes to fill the pool, write an equation to find the total gallons of water needed.

• Total gallons = 5t^2

• Total gallons = 10t
