Answer:
Step-by-step explanation:
Let "s" be the the speed of the car taking the shorter route in [tex]\frac{mi}{hr}[/tex],
Let "s-2" the speed of the cat taking the longer route in [tex]\frac{mi}{hr}[/tex],
Let "d" be the distance of the shorter route in miles and "d+43" be the distance of the longer route in miles.
Now, Equation for car taking the shorter route is given as:
[tex]d=s{\times}5[/tex] (1)
and Equation for car taking the longer route is given as:
[tex]d+43=(s-2){\times}6[/tex] (2)
Now, substitute equation (1) in (2), we get
[tex]5s+43=6s-12[/tex]
⇒[tex]43+12=s[/tex]
⇒[tex]s=55[/tex]
Therefore, equation (1) becomes,
[tex]d=5s=5(55)=275[/tex]
Thus, the shorter route is =275 miles and the longer route is =d+43=275+43= 318 miles.
