Carl drove from his house to work at an
average speed of 35 miles per hour. The drive took him 25 minutes. If
the drive home took him 30 minutes and he used the same route in
reverse, what was his average speed going home?








Sagot :

Speed is distance over time v=d/t d=vt d=35mph (25min)(1hr/60min) d=14.583mi Using the same distance and t=30min v=d/t v=14.583mi/(30min (1hr/60min)) v=29.166mph
