Write your answer in simplest form.

Answer 1

2

Explanation:

Answer 2

2 tons of dirt per hour

Explanation:

helpful to know: 1/6 hours = 10 minutes

you can create a proportion to find unit rate by using (tons of dirt ÷ time)

we'll use 'd' to represent amount of dirt and use minutes

1/3÷10 = d/60

1/3÷10 = 1/3 × 1/10 = 1/30

we now have:

1/30 = d/60

we can cross-multiply to get:

30d = 60

d = 2
