Connor and Matt walks a 12-mile course as part of a fitness program. Matt walks 1 mi/h faster than Connor, and it takes him 1 hour less than Connor to complete the course. How long does it take Connor to complete the course?

Answer 1

since time = distance/speed,

12/s - 1 = 12/(s+1)

Hint: 3 is one less than 4.

It takes Connor 4 hours to complete the course?
