Total time = upstream time + downstream time
he rowed the same distance both ways.
upstream time = D/4
downstream time = D/6
total time = D/4 + D/6 = 3D/12 + 2D/12 = 5D/12 = 3 hours
D = 3*12/5 = 36/5 or 7.2 miles
where D is the one-way distance. The total distance he rowed is 2*D = 72/5 or 14.4 miles
Answer:
-2.6, -1.7, -0.81, 0.24, 1.89
Step-by-step explanation:
The answer for number 3 is 3.c
Length = x - 2
Width = x - 5
Explanation:
Area = x^2 - 7x + 10
Area = (x - 2)(x - 5)
Area = Length x Width
Length = x - 2
Width = x - 5
