Answer:
48 miles per hour
Step-by-step explanation:
José left Westcliffe on his bicycle riding at an average rate of 8 miles per hour five hours before his father left by automobile. The father overtook José in exactly one hour. This means Jose was riding
5 hours + 1 hour = 6 hours.
Use formula
[tex]D=r\cdot t,[/tex]
where
D = distance
r = rate
t = time
In Jose's case,
D = unknown
r = 8 miles per hour
t = 6 hours
Hence,
[tex]D=8\cdot 6=48\ miles[/tex]
In Jose's father case,
D = 48 miles
r = unknown
t = 1 hour (father overtook José in exactly one hour)
Hence,
[tex]48=r\cdot 1\\ \\r=48\ miles \ per \ hour[/tex]
