You can make a ratio of red to overall colors and then that will give you the fraction, you might have to simplify it
Speed = Distance / Time
Distance = Speed*Time
For this problem, we should bear in mind that current speed has an impact on the boat speed...
for upstream, the boat goes against the current, and so its speed is
U = V - C
where V is the speed of the boat
C is the current speed
for downstream, it will be:
D = V + C
Convert the problem into mathematical equations:
4D + 3U = 116
3D + 4U = 108
4(V+C) + 3(V-C) = 116
4V + 4C + 3V -3C =116
7V + C = 116
3(V+C) + 4(V-C) = 108
3V + 3C + 4V - 4C = 108
7V - C = 108
Solving the equations:
7V + C = 116
7V - C = 108
14V = 224
V = 16km/hr —-> speed of boat
to get C:
7(16) + C = 116
C = 4km/hr
Do you mean how many different words can be made from using only 3 letters from the word "question"? Are they supposed to be the same 3 letters?

Answer:
4.5miles
Step-by-step explanation:
divide 28 by 3 to get 9.333 minutes each mile
then divide 42 by 9.333 to get 4.50 miles
