If the subway travels and average speed of 45mph and it allows you to get to work at 8:30, when you leave your house at 7:45. One day the subway was having problems and could go 35mph. how early would you have to leave your house to make it to work on time?

at the regular speed it took 45 min or 3/4 hour

so the distance is 45*3/4 mi or 135/4 miles

at a speed of 35 mph it would take

135/4 รท 35 hours or .96429 hours

which would be 57.9 minutes

so just back up that time from his work start of 8:30

BTW, how would he have known that the subway was going to have a problem, and left earlier to still make it on time ??????
