Answer:</h2>
- Trip to work has rate: 24 mph
- Trip back to home has rate: 18 mph
- Distance to work is: 480 m
<h2>
Step-by-step explanation:</h2>
We know that speed is defined as the ratio of distance to time.
i.e.
Let the distance traveled to work be: x m.
Now, while going to work it takes a person 20 minutes.
This means that the speed of the person while going to work is:
Also, the time taken to come back home is: 30 minutes.
This means that the speed of person while riding to home is:
Also, it is given that the rate back is 8 mph slower than the trip to work.
This means that:
i.e.
Hence, the distance to work is: 480 m.
Also, the rate while going to work is:
and the trip back to home is covered with the speed:
Answer:
There are no x-intercepts.
Step-by-step explanation:
To find an x intercept we have to find where y = 0
So set the equation equal to zero
Since the number under the radical is negative, we know there are no real solutions, and therefore there are no x-intercepts.
This is shown on the graph.
