A rowing team rowed 90 miles while going with the current in the same amount of time as it took to row 10 miles going against th
e current. The rate of the
current was 4 miles per hour. Find the rate of the rowing team in still water.
1 answer:
Answer:
5mph
Step-by-step explanation:
Let speed of boat in still water is s.
Distance proportional to speed
90/10 = (s+ 4)/(s - 4)
=> 9s - 36 = s + 4
=> 8s = 40
=> s= 5 mph

Answer:
A
Step-by-step explanation:
Vertex appear to be at (5,115)
A) h = -b/2a
= -(20)/2(-2) = 5
k = -2(5²) + 20(5) + 60 = 110
12,750 tickets were sold
0.85 x 15,000
1/2 - 3/8 = 4/8 - 3/8 = 1/8
you have to find a common denominator before you can subtract. in this case it is 8
