In total, he traveled 333 miles for 9 hours.

**Steve**, Monday, August 13, 2012 at 3:34pmif he traveled x miles at 29 m/h and y miles at 53 m/h, then

x+y=333 and, since time = distance/speed,

x/29 + y/53 = 9

so,

x/29 + (333-x)/53 = 9

x = 174

y = 159

check:

174+159 = 333

174/29 + 159/53 = 6+3 = 9
