The speed of the walker and the biker will be 16.67 miles per hour and 25 miles per hour.
Speed is the distance that a particle or body travels in one hour. It has a scalar value. It is the time-to-distance ratio.
We know that the speed formula
Speed = Distance/Time
A biker’s speed is 1.5 times faster than a walker’s speed.
Let y be the speed of the biker and x be the speed of the walker. Then the equation is given as,
y = 1.5x
They begin going simultaneously from the same location in the same direction, and after 1.5 hours, there are 12.5 miles separating them.
y - x = 12.5 / 1.5
1.5x - x = 25/3
0.5x = 25/3
x = 16.67 miles per hour
Then the speed of the biker will be given as,
y = 1.5 (16.67)
y = 25 miles per hour
The speed of the walker and the biker will be 16.67 miles per hour and 25 miles per hour.

Answer: Speed of walker and biker will be 16.67 miles per hour and 25 miles per hour respectively.
Step-by-Step explanation:
Leave the speed of a walker alone x
Let the speed of a biker be 1.5x
They are moving a similar way,
thus, their Relative speed will be
1.5x - x =0.5x
Time taken = 1.5 hours
Separation between them = 12.5 miles
As we probably am aware the equation for "Distance":
*Picture attached*
Consequently, the Speed of the walker be 16.67 miles every hour
Speed of biker be
1.5 times 16.67=25 miles per houe
A. 6(k + s)
B. s(6 + k)
C. k(6 + s)
D. k · (6 + k) · s
Answer:
This relationship is a function
Step-by-step explanation:
By definition a relation is defined as a function if and only if for each input value x there is only one output value y.
In this case we observe the following ordered pairs
(0,2),(1,4), (2,5), (3,6)
We see that each value x has only a value of y.
Therefore this relationship is a function
