Answer:
Rate of Bill's boat = 14 miles per hour
Speed of the current = 2 miles per hour
Step-by-step explanation:
Let x = the rate of the boat in still water and y = the rate of the current.
Distance traveled = 24 miles
Time taken for upstream motion = 2 hour
Time taken for downstream motion = 1.5 hour
Velocity of upstream motion = x - y
Velocity of downstream motion = x + y
We have
Displacement = Time x Velocity
Upstream motion
24 = 2(x-y)
x - y = 12 ----------------------------eqn 1
Downstream motion
24 = 1.5(x+y)
x + y = 16 ----------------------------eqn 2
eqn 1 + eqn 2
2 x = 28
x = 14 miles per hour
Substituting in eqn 2
14 + y = 16
y = 2 miles per hour
Rate of Bill's boat = 14 miles per hour
Speed of the current = 2 miles per hour
Answer:
10V3 cm= square root of 300
Step-by-step explanation:
the diagonal ^2=10^2+(10V2)62=100+200=300
the diagonal is 10 V3
Answer: idk jus needed the points so im answering
Answer:
option B
Step-by-step explanation:
the slope is -2, so the equation must have -2x in it.
This narrows it down to option C and B
the intercept is at -5, not +5 so the correct answer is y = -2x - 5
