1 kilometer =5/3 week
Step-by-step explanation:
Given that the crew paves 3/5 kilometer of a road in 1 week then this can be written as;
3/5 k = 1 week
For 1 kilometer of a road,
3/5k = 1 week
1k=?
perform cross product as;/multiplication equation
1*1 / 3/5
1*5/3
5/3, 1 2/3 weeks
A division equation will be'
3/5 kilometers = 1 week
Divide both sides by 3/5
1 kilometer =5/3 week

Let d = the length of the trail, miles
Note that
distance = speed * time
or
time = distance / speed.
The time, t₁, to travel the trail at 3 miles per hour is
t₁ = d/3 hours
The time, t₂, to travel back at 5 miles per hour is
t₂ = d/5 hours
Because the total time is 3 hours, therefore
t₁ + t₂ = 3
d/3 + d/5 = 3
d(1/3 + 1/5) = 3
d(8/15) = 3
Multiply each side by 15.
8d = 3*15 =45
d = 45/8 = 5 5/8 miles or 5.625 miles
Total distance = 2*d = 11.25 miles or 11 1/4 miles.
t₁ = 5.625/3 = 1.875 hours or 1 hour, 52.5 minutes
t₂ = 5.625/5 = 1.125 hours or 1 hour , 7.5 minutes
Answers ;
Time to travel at 3 miles per hour = 1.875 hours (1 hour, 52.5 minutes)
Time to return at 5 miles per hour = 1.125 hours (1 hour, 7.5 minutes)
Total distance traveled = 2*d = 11.25 miles.
