Convert and Calculate: Finding Average Daily Progress in 5km Wall Construction

Question

Nigel builds a 5 km long wall over a period of two days.

How many meters on average does he build each day?

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Convert the total length of the wall Nigel builds from kilometers to meters.
  • Step 2: Calculate the average number of meters built each day.

Now, let's work through each step:

Step 1: Nigel builds a wall that is 5 kilometers long. Since 1 km=1000 m1 \text{ km} = 1000 \text{ m}, we convert kilometers to meters:

5 km=5×1000 m=5000 m5 \text{ km} = 5 \times 1000 \text{ m} = 5000 \text{ m}

Step 2: Since the wall is built over 2 days, we divide the total length in meters by the number of days to find the average:

Average meters per day=5000 m2 days=2500 m/day\text{Average meters per day} = \frac{5000 \text{ m}}{2 \text{ days}} = 2500 \text{ m/day}

Therefore, on average, Nigel builds 2500 meters of the wall each day.

Thus, the correct answer is choice 3\boxed{3} with 2500 m per day.

Answer

2500
