: Jeff leaves his house on his bicycle at 8:30 A.M. and averages 5 miles per hour. His wife, Joan, leaves at 9:00 A.M. following the same path and averaging 8 miles per hour. At what time will Joan catch up with Jeff? This question is from textbook Mathematical Ideas
You can put this solution on YOUR website! Jeff leaves his house on his bicycle at 8:30 A.M. and averages 5 miles per hour. His wife, Joan, leaves at 9:00 A.M. following the same path and averaging 8 miles per hour. At what time will Joan catch up with Jeff?
Jeff Data:
Distance=?; Rate=5mph ; Time=x hrs.
Joan Data:
Distance=?; Rate=8 mph; Time=x-1/2 hrs.
EQUATIon:
Jeff distance = Joan distance
5x=8(x-1/2)
5x=8x-4
-3x=-4
x=4/3 hrs. = 80 minutes
