Answer: 707 km/h
Step-by-step explanation:
let c = speed of current
16.5 + c = speed of sailboat downstream
16.5 - c = speed of sailboat upstream
distance = travel time * speed
﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋
2(16.5 + c) = 5(16.5 - c)
33 + 2c = 82.5 - 5c
7c = 49.5
c = 7.07 km/h
Cross multiply? 9x2=18/3= 6
Answer:
The answer is 10 minutes.
Step-by-step explanation:
First, convert the known amount of time to a fraction.
6/21 (min over hot dogs).
Set up a proportion.
6/21 = m/35 (m being the number of minutes)
Cross multiply.
210 = 21m
Solve for m. (divide each side by 21)
m = 10
