Question

A gardening company plants 10 trees in 2 hours. How long will it take to plant 150 trees?

Answer 1

If 10 trees takes 2 hours, then 5 trees takes 1 hour. 150 ÷ 5 = 30.

It will take 30 hours to plant 150 trees.

Answer 2

30 hours will it take to plant 150 trees.

Explanation:

Unit rate defined as the rates are expressed as the quantity as 1 such that 2 miles per second or 4 km/hr

As per the statement:

A gardening company plants 10 trees in 2 hours.

Unit rate per trees =
`\frac{\text{Number of hours}}{\text{number of trees}} =(2)/(10) = (1)/(5)`

we have to find the time it will take to plant 150 trees.

`\text{Number of hours} = \text{Unit rate per trees} * 150`

Substitute the given values we have;

`\text{number of hours} = (1)/(5) * 150 = 30`

Therefore, 30 hours will it take to plant 150 trees.
