Calculation of Trips After Lunch on the Dump Truck

To calculate the number of trips made by the dump truck after lunch, we can use the information provided.

Given: - Total trips made in a day: 9 - Total sand brought in a day: 360 centners - Sand brought before lunch: 160 centners

We can calculate the sand brought after lunch and then determine the number of trips made after lunch.

Calculation Steps

1. Calculate Sand Brought After Lunch: - Total sand brought = Sand brought before lunch + Sand brought after lunch - Sand brought after lunch = Total sand brought - Sand brought before lunch - Sand brought after lunch = 360 centners - 160 centners - Sand brought after lunch = 200 centners

2. Calculate Trips After Lunch: - Trips made after lunch = (Sand brought after lunch) / (Sand brought per trip) - Sand brought per trip = Total sand brought / Total trips made - Sand brought per trip = 360 centners / 9 trips - Sand brought per trip = 40 centners per trip - Trips made after lunch = 200 centners / 40 centners per trip - Trips made after lunch = 5 trips

Therefore, the dump truck made 5 trips after lunch.
