Answer:
2 tons of dirt per hour
Step-by-step 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
