Question

I don;t get it...the part that confuses me is the "per minute" ..i don;t get the relationship to the mile thing....totally stumped..sorry can't even offer an idea how to do this one...help and thank you

Answer 1

92 feet per minute is a rate, it means that each minute you travel 92 ft, they just the equivalent in miles per hour, or mi/hour

92 ft / 1 minute
= (92/5280) ft / (1/60) hour
---- 1 ft = 1/5280 miles, so 92 ft = 92/5280 miles
---- 1 minute = 1/60 hour

= (92/5280)(60) mph
= appr 1.05 mph
