Molly shot 20 baskets in 4 minutes. Nico shot 42 baskets in 6 minutes. How many more baskets did Nico shoot per minute?

Molly - 20/4

Nico - 42/6

Now, lets do cross multiplication.

20/4 = x/1 42/6 = x/1

4 (x) = 20 (1) 6 (x) = 42 (1)

4x=20 6x = 42

4x/4 = 20/4 6x/6 = 42/6

x=5 x=7

Therefore, Nico shot 2 more baskets per minute than Molly.
