Respuesta :
The distance Hailey and Levi are from the stadium as they drive, can be
shown using a graph.
- Please find attached the graph of the function of Hailey's and Levi's distance from the stadium, created with MS Excel.
- The distance they both are from the stadium at the moment they are at an equal distance from the stadium is 150 miles.
Reasons:
The given information are;
Distance of Hailey from the stadium at noon = 300 miles
Distance of Levi from the stadium at noon = 450 miles
Hailey's speed = 25 mph
Levi's speed = 50 mph
Required:
(a) Draw the graph of the function of their distance from the stadium
(b) Determine the distance how far from the stadium at which they are at an equal distance from the stadium.
Solution:
Based on the question, the required function are;
Hailey's distance from the stadium, H = 300 - 25·t
Levi's distance from the stadium, L = 450 - 50·t
The graph of the distance of Hailey and Levi can be plotted on MS Excel using the above functions.
At the time they are equal distance from the stadium, we have;
H = L
Which gives;
300 - 25·t = 450 - 50·t
50·t - 25·t = 450 - 300 = 150
25·t = 150
[tex]\displaystyle t = \frac{150}{25} = 6[/tex]
Therefore, after 6 hours, Hailey and Levi are at an equal distance from the stadium.
The distance from the stadium, d = 300 - 25 × 6 = 150
- The distance both Hailey and Levi are from the stadium, the moment they are an equal distance from the stadium, d = 150 miles
