If the distance between his work and home is d=30+mil, and if Mark leaves home at 9am and arrives at work at 9:45am, the time t is 45min.
To find how fast did he travel, calculate speed (velocity) v by using a formula
v=d%2Ft
v=30mil%2F45min.......you need a time in hours....45min=0.75h
v=30mil%2F0.75h
v=40mph
