It takes George 8 miinutes longer to drive to work during the rush hour than to get home from work the same route. If his average speed going to work is 45 mph, and his average speed driving home is 54 mph, how far does George live from work?
Answer provided by our tutors
2 * distance = 45 * 8/60 + 54* 8/60
2 * distance = 8/60 (45 + 54 )
2 * distance = 8 * 99 /60
distances = 8 * 99 / 120 = 6.6 miles
