How many hours can he run now? ** He increases the time he can run by 8*.75=<<8*.75=6>>6 hours
How many hours can he run now? ** So he can now run 8+6=<<8+6=14>>14 hours
How fast is he now? ** His speed is now 8+4=<<8+4=12>>12 mph
How far can he run now? ** So he can run 14*12=<<14*12=168>>168 miles
