Answer: First route.
Step-by-step explanation:
Since, if the time taken is less then the route will be called faster.
[tex]\text{Also, Time }=\frac{ \text{Distance}}{\text{speed}}[/tex]
Here, In first route,
70 miles is covered at 55 miles per hour,
Hence, the total time taken = 70/55 = 1.27272727≈1.27 hours
In second route,
85 miles is covered at 65 miles per hour,
Hence, the total time taken = 85/65 = 1.30769231 ≈ 1.31 hours
Since, 1.27 < 1.31
Thus, the first route is faster than second route.
