Final answer:
To transport 53.9 cubic meters of rock and soil, Ivanna would require the dump truck to make 5 trips, as each trip can carry 11 cubic meters and you cannot do a fraction of a trip.
Step-by-step explanation:
The student is asking how many trips a dump truck will need to make to haul 53.9 cubic meters of rock and soil with an average density of 1000 kg/m³, given the truck has a capacity of 11 m³. To determine the number of trips, divide the total volume of material by the capacity of the truck.
Total Volume Needed to be Transported: 53.9 m³
Truck Capacity: 11 m³
Number of Trips: 53.9 m³ / 11 m³ = 4.9 trips
As the truck cannot make a fraction of a trip, Ivanna needs to round up. Therefore, the dump truck will have to make 5 trips to move all the material.
