Answer 2

Calculating the Total Distance Cleaned by Three Machines

To calculate the total distance cleaned by the three machines, we can follow these steps:

1. Calculate the Distance Cleaned by the First Machine - The first machine cleaned 3 kilometers and 500 meters of road.

2. Calculate the Distance Cleaned by the Second Machine - The second machine cleaned 1 kilometer and 170 meters more than the first machine.

3. Calculate the Distance Cleaned by the Third Machine - The third machine cleaned 1 kilometer and 800 meters less than the second machine.

4. Add the Distances Cleaned by All Three Machines

Let's calculate the total distance cleaned by the three machines.

Calculation

1. Distance cleaned by the first machine: 3 km 500 m 2. Distance cleaned by the second machine: (3 km 500 m) + (1 km 170 m) 3. Distance cleaned by the third machine: (3 km 500 m) - (1 km 800 m)

Now, let's perform the calculations.

Results

1. Distance cleaned by the first machine: 3 km 500 m 2. Distance cleaned by the second machine: 3 km 500 m + 1 km 170 m = 4 km 670 m 3. Distance cleaned by the third machine: 3 km 500 m - 1 km 800 m = 1 km 700 m

Now, let's add up the distances cleaned by all three machines to find the total distance cleaned.

Total Distance Cleaned

- Total distance cleaned by all three machines: 3 km 500 m + 4 km 670 m + 1 km 700 m

Final Answer

The total distance cleaned by the three machines is 9 kilometers and 870 meters.
