Answer:
Hence Distance traveled at speed 115 mph is <u>345 miles</u> and Distance traveled at speed 105 mph is <u>210 miles</u>.
Step-by-step explanation:
Given:
Total Distance = 555 mile
Total time = 5 hour
Let time taken to travel at 115 mph be t
So Time taken to travel at 105 mph will be equal to difference between Total time and time taken to travel at 115 mph.
Time taken to travel at 105 mph =
Distance traveled in speed 105 mph will be equal to speed multiplied by time taken to travel at 105 mph.
Framing in equation form we get;
Distance traveled in 115 mph =
Also;
Distance traveled in speed 105 mph will be equal to speed multiplied by time taken to travel at 105 mph.
Framing in equation form we get;
Distance traveled in 105 mph =
Now Total Distance traveled is equal sum of Distance traveled in 115 mph and Distance traveled in speed 105 mph
Time taken to travel at 115 mph = 3 hrs.
Time taken to travel at 105 mph =
Now Distance traveled in 115 mph =
Distance traveled in 105 mph =
Hence Distance traveled at speed 115 mph is <u>345 miles</u> and Distance traveled at speed 105 mph is <u>210 miles</u>.
Answer:
The graph of y = 1/2f(x) is the graph y = x and y = -x for -4 ≤ y ≤ 0
Step-by-step explanation:
Here we note that when y = 0, x = 0
when y = -4, x = -2
The equation is therefore of the form y = m·x + c
m = slope
c = y intercept = 0
Hence the first line is y = 2·x
The second line on the right is the mirror of the first on the left with slope;
Hence the second line on the right is y = -2·x
Hence for y = 1/2 f(x) we have;
y = 1/2 × 2·x = x and y = 1/2 ×-2·x = -x
Graphing the functions, we have
