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

1/1/3 of a tree

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 (2)/(3)* 2`

`\\ \rm\Rrightarrow (2(2))/(3)`

`\\ \rm\Rrightarrow (4)/(3)`
