Complete the parts below. Write your answers as whole numbers or fractions in simplest form.
(a)A construction crew built 10 kilometers of road in 25 days. Give two different unit rates using this relationship.
One unit rate:
(Choose one)
per
(Choose one)
Another unit rate:
(Choose one)
per
(Choose one)
(b)Assume the crew builds the same amount of road each day. How many kilometers of road can they build in 20 days?
(a) One unit rate: 10 kilometers per 25 days
Another unit rate: 2 kilometers per 5 days
(b) If the crew builds the same amount of road each day, they can build 0.4 kilometers of road in 20 days.

My apologies, I made a mistake in my previous response.
If the crew builds the same amount of road each day, they can build 0.5 kilometers of road in 20 days.
To find the unit rate, we need to determine the amount of road built per day. We can do this by dividing the total distance of 10 kilometers by the number of days, which is 25:
10 km ÷ 25 days = 0.4 km/day
So, the first unit rate is 0.4 kilometers per day.
For the second unit rate, we can reverse the calculation and find the number of days it takes to build 1 kilometer of road. To do this, we divide the number of days by the total distance:
25 days ÷ 10 km = 2.5 days/km
So, the second unit rate is 2.5 days per kilometer.
Now, let's move on to part (b):
If the crew builds the same amount of road each day, which is 0.4 kilometers per day, we can calculate the total distance they can build in 20 days by multiplying the unit rate by the number of days:
0.4 km/day × 20 days = 8 kilometers of road.
Therefore, the crew can build 8 kilometers of road in 20 days.
