A crew needs to pick up litter along one side of a section of highway that is 49.5 kilometers long.

How many kilometers must the crew clean each day in order to finish the job in 5.5 days?

A 0.11km
B 0.9 km
C 9.0 km
D 11.2 km

49.5 / 5.5 = 9 km/day

To find out how many kilometers the crew must clean each day in order to finish the job in 5.5 days, we can divide the total distance of 49.5 kilometers by the number of days it will take to complete the job.

Calculating the daily distance would involve dividing the total distance by the total number of days:

Daily distance = Total distance / Total number of days

Daily distance = 49.5 km / 5.5 days

Simplifying this equation will give us the answer:

Daily distance = 9 km (rounded to one decimal place)

Therefore, the crew must clean approximately 9.0 kilometers each day. So, the correct answer is option C: 9.0 km.
