Tonisha leaves Maryville at 7:15 a.m. headed back to college
after summer break. Since she is towing a trailer with all of her
belongings, she is limited to an average speed of 45 mph. Her
friend Sheila leaves Maryville an hour later taking the same
route averaging the speed limit of 60 mph.
At what time will Sheila pass Tonisha?

Question

anonymous · Answer

45x = 60 (x - 1)

45x = 60x - 60

15x = 60

x = 4

7 : 15 + 4 hours is 11: 15
