Answer:
Wesley will take another 5 hours to cover final leg.
Step-by-step explanation:
Distance between California to Utah is 673.10 miles.
Wesley covers a distance with 67.20 miles per hour in 3 hours, so distance covered will be = Speed × time
= 67.20×3 = 201.6 miles
For next 2 hours Wesley's average speed was 69.5 miles per hour.
So distance covered by him = 69.5 × 2 = 139 miles
Now remaining distance to cover by him = 673.10 - (201.60 + 139)
= 673.10 - 340.60 = 332.50 miles
Now Wesley covers this remaining distance 332.50 mile with the speed of 66.5 miles per hour.
So time taken to cover this distance = [tex]\frac{Distance}{Speed}=\frac{332.50}{66.5}[/tex]
Distance covered = 5 hours.
Therefore, time taken to cover this final leg will be 5 hours.
