Please help me on my activity with my General Mathematics subject about rational function in real life. Please give accurate complete solutions. Thank you!

Example2: A boat goes 250 miles downstream, in the same time it can go 165 miles upstream. The speed of the current is 6 miles per hour. What is the speed the boat in the still water? Solution: t1 = t2 2490 = 85x 165 250 2490 85x X-6 x+6 85 85 165(x + 6) = 250(x - 6) 29.29 = X 165x + 990 = 250x - 1500 990 + 1500 = 250x - 165x Therefore, the speed of the boat in still water is 29.29 miles per hour.C] Solve for what is being asked. 13) Janice takes 2 hours to plant 50 seedlings. Zoren takes 3 hours to plant 45 seedlings. Working together, how long should it take them to plant 150 seedlings? (5pts) 14) A mixing tank currently contains 200 gallons of water in which 40 pounds of sugar have been mixed. A tap will open pouring 15 gallons of water per minute into the tank at the same time sugar is being poured into the tank at the rate of 2 pounds per minute. Find the concentration (pound per gallon) of sugar in the tank after 8 minutes. Is the concentration after 8 minutes greater than the beginning concentration?

Solution: Both R3001 = RPedro + RMaria 7 Therefore, if both work together, they can nish the report in 1.71 hours only.
