Write an equation

John and Mary decide to race. John has a 300 ft head start, and runs at a pace of 250ft per minute. Mary runs at a pace of 400 ft per minute. How long before Mary catches up to John?

• 250 + 300m = 400

• 300m + 400 = 250m

• 250 + 400m = 300m

• 300 + 250m = 400m

A bucket filled with 300oz of water is poured into an empty bucket at a rate of 7oz per second. How long before both buckets have the same amount of water?

• 300x - 7 = 0

• 300 - 7x = 7x

• 7x = 300 - 7

• 7x - 7x = 300

Write & solve an equation

Bowman had 30 pieces of candy and gave away x pieces. Rose started with 40 pieces of candy and gave away twice as many pieces as Bowman. How many pieces did Bowman give away if they ended up with the same amount of candy left?

• 40 + 2x = 30 + x

  x= 3

• 30 - x = 40 - 2x

  x= -10

• 30 - 2x = 40 - x

  x= 3

• 30 - x = 40 - 2x

  x= 10
