Answer :
[tex]formula\ for\ average\ speed= \frac{distance}{time}\\\\
Hector:\\\\
v_H=\frac{8miles}{85\ minutes}\approx0,09\frac{mile}{min}\\\\
Mario:\\\\
v_M=\frac{6miles}{55minutes}=0,1\frac{miles}{min}\\\\
Mario\ has\ faster\ speed.[/tex]
Since v=d/t
We can change the times from minutes to hours so that the answers will be in mph (but it isn't necessary)
Hectors speed=8/1.42=5.6mph
Marios speed=6/0.92=6.5mph
Therefore mario has the greater average speed.
Hope this helps :-)
