Algebra Problem Help?
If you jog 12 mi at an average rate of 4 mi/h and walk the same route back at an average rate of 3 mi/h, you have traveled 24 mi in 7 hours and your overall rate is 24/7 mph. What is your overall average rate if you travel d mi at 3 mi/h and d mi at 4 mi/h?
thanks!

The same because you still traveled 12 miles at 4 mph and 12 at 3 mph.
