Answer 1

Luigi has the fastest growing plant

Explanation:

Luigi and Mario are growing plants for a science fair.

Mario measured his at one foot three inches in one week.

1 foot = 12 inches

Hence, the height of Mario's plant in one week

= 12 inches + 3 inches = 15 inches

Luigi's plant grew 11 inches in five days.

7 days = 1 week

5 days = 11 Inches

7 days = x

5x = 7 × 11

x = 77/5

x = 15.4 inches
