When e dey waka for downhill slopes, e fit race with 12 miles per hour pass wetin e dey waka for flat sand. And when e dey ride for uphill inclined slow, e dey waka with speed wey dey 18 miles per hour less pass when e dey ride for flat sand. If Conner dey ride im dune buggy one-third of the time for flat sand, one-third of the time for uphill slopes, and one-third of the time for downhill slopes, wetin be im average speed for miles per hour? <response>: ```12 mph wey pass 60mph na 60+12=72 mph.
18 mph wey slow pass 60 mph na 60-18=42 mph.
