Complete Question
Alberta is going to have dinner at her grandmother's house, but she is running a bit behind schedule. As she gets onto the highway, she knows that she must exit the highway within 55 min if she is not going to arrive late. Her exit is 43 mi away. How much time would it take at the posted 60 mph speed?
Answer:
The time it would take at the given speed is [tex]x = 43.00 \ minutes[/tex]
Explanation:
From the question we are told that
The time taken to exist the highway is [tex]t = 55 min[/tex]
The distance to the exist is [tex]d = 43\ mi[/tex]
Alberta speed is [tex]v = 60 mph[/tex]
The time it would take travelling at the given speed is mathematically represented as
[tex]t_z = \frac{d}{v}[/tex]
substituting values
[tex]t_z = \frac{43}{60}[/tex]
[tex]t_z = 0.71667\ hrs[/tex]
Converting to minutes
1 hour = 60 minutes
So 0.71667 hours = x minutes
Therefore
[tex]x = 0.71667 * 60[/tex]
[tex]x = 43.00 \ minutes[/tex]
