Answer :
Answer:
2.70 hours to travel 180 mi.
Step-by-step explanation:
The distance traveled (d) varies directly as the time (t) of travel, by the following formula:
[tex]s = \frac{d}{t}[/tex]
In which s is the velocity.
It takes 63 min to travel 70 mi.
So i am going to find the velocity in miles per minute
[tex]s = \frac{70}{63} = 1.11[/tex]
how many hours would it take to travel 180 mi?
I am first going to find the time in minutes, then divide by 60 to pass to hours.
[tex]s = \frac{d}{t}[/tex]
[tex]st = d[/tex]
[tex]t = \frac{d}{s}[/tex]
[tex]t = \frac{180}{1.11}[/tex]
[tex]t = 162.16[/tex]
It takes 162.16 minutes = 162.16/60 = 2.70 hours to travel 180 mi.
