Two students are preparing for a marathon. Hector ran 8 miles in 85 minutes. Mario ran 6 miles in 55 minutes. Who has the faster average speed?

Sagot :

luana
[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 :-)
