Answer:
d = 56x + 412
Step-by-step explanation:
To find the total number of miles traveled on Monday and Tuesday, use a linear equation to write the function.
y = mx+b where m is the speed or rate of change and b is the starting point.
The starting point on Tuesday is 412 miles. This is b.
The number of miles traveled on Tuesday is found by calculating 56 miles times the number of hours traveled. This is the slope or m.
So the equation is d = 56h + 412.
<span>A motorboat
travels 222 km in 6 hours going upstream.
Rate = distance/time = 222/6 = 37 km/hr
----------------------
It travels 390 km going downstream in the same amount of time.
Rate = distance/time = 390/6 = 65 km/hr
---------
What is the rate of the boat in still water and what is the rate of the
current?
Equations:
Upstream: b-c = 37 km/hr
Downstrm: b+c = 65 km/hr</span>
<span>Add and solve
for "b":
(2)b = 102 km/hr
b = 51 km/hr (speed of the boat in still water)
-----
Solve for "c":
b+c = 65
51 + c = 65
c = 14 km/hr (speed of the current)</span>
