Question

Chris is trimming trees. He can trim 2/3 of a tree in 30 minutes. What is Chris’s rate for trimming trees in trees per hour?

Answer 1

Answer:

1/1/3 of a tree

Step-by-step explanation:

30 minutes = 2/3 of a tree

Since 1 hour = 60 minutes,

60 minutes = 2/3 × 2

                   = 4/3

                   = 1/1/3 of a tree

Answer 2

• Speed per 30min=2/3
• Speed per hour

$\\ \rm\Rrightarrow \dfrac{2}{3}\times 2$

$\\ \rm\Rrightarrow \dfrac{2(2)}{3}$

$\\ \rm\Rrightarrow \dfrac{4}{3}$
