Answer:The expression that can be used to determine how fast an elephant runs in miles per hour is 100 miles per hourSolution:Given that, Distance covered by an elephant in 36 seconds is equal to 1 mile Therefore, distance covered by the elephant in 1 second is  [tex]\frac{1}{36}[/tex] mileTherefore, distance covered by the elephant in 60 seconds (60 seconds = 1 minute) is [tex]\frac{1}{36} \times 60=\frac{5}{3} \text { miles }[/tex]Therefore, distance covered by the elephant in 60 minute (60 minute = 1 hour) is[tex]\frac{5}{3} \times 60=100 \text { miles per hour }[/tex]Hence the expression that can be used to determine how fast an elephant runs in miles per hour is 100 miles per hour
