Roger is planting flowers down the side of his house.he can plant 3 flowers every 2 minutes. If roger continues to plant the flowers at the same rate, how many flowers will roger plant in 30 minutes
because he can plant 3 flowers in 2 minutes 3/2 or 1.5, so he can plant one flower and a half in one minute, then it is just the concept of multiplying 1.5 and 30!
