A motorboat heads upstream a distance of 24 miles on the Guadeloupe River, whose current is running at 3 mph. The trip up and back takes 6 hours. Assuming that the motorboat maintained a constant speed relative to the water, what was its speed?

9mph

Step-by-step explanation:

Let speed of boat=x mph

Speed of current=3 mph

Upstream speed=(x-3) mph

Downstream speed =(x+3)mph

Distance=24 miles

Total time=6 hours

According to question

Using the identity:

Speed cannot be negative

Therefore, the speed of boat=9mph

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
