Answer:
Jose traveled 52.5 miles in 1 hour
Step-by-step explanation:
What we're actually doing here is finding the "unit rate": the speed in mph:
35 mi 105 mi
------------ = ------------ = 52.5 mph = 52.5 miles in 1 hour
2/3 hr 2 hr
Jose traveled 52.5 miles in 1 hour
12% = 0.12
x - Number of shoes sold
f(x) = 0.12x + 5.50
Total distance = 20 km = 20 000 m
walk = 800 m
cycle = 20 000 - 800 = 19 200m
percentage of the journey =

x 100% = 96%
