Step-by-step explanation:
The complete question is attached below.
The x-axis represents the time in hours and y-axis represents the distance in kilometers.
The first question asks how many kilometers, does Kendrick walk per hour. The straight line represents the distance traveled at various amounts of time.
The point marked on the graph is against time = 1 hour and Distance = 5 km. So this shows:
Kendrick walks 5 kilometers in 1 hour.
In next part, we have to find how much time Kendrick takes to walk 1 kilometer.
Since, we know that:
Kendrick walks 5 kilometers in time = 1 hour
Dividing both sides by 5, we can write:
Kendrick walks 1 kilometer in time = 1/5 hour = 0.2 hour
So, Kendrick takes 0.2 hours to walk 1 kilometer.
Answer:
Step-by-step explanation:
Let's solve the second equation for x
Now let's replace this in the first equation.
Distribute the 5
Individually solve the fractions.
Solve;
Subtract 20 from both sides.
Divide both sides by -7
Now replace the value of y in any of the two equations to find x.
add on both sides.
Multiply by the reciprocal fraction of 3. I suppose you know that 3 is 3/1 hence the inverted fraction would be 1/3
