In order to determine the number of days the team will take to drive 4800 miles, use the following formula:
time = distance / speed
where:
distance = 4800 mi
speed = 40 mi/h
replace the previous values into the formula for the time:
time = 4800 mi/ 40 mi/h
time = 120 h
However, you need the answer in days, then, take into account that
1 day = 24 hours
then, you have:
120 h · (1 day/ 24 h) = 5 days
Hence, the team will take 5 days to drive 4800 miles
