Answer:
3 hours.
Step-by-step explanation:
Since they are heading away from each other, their relative velocity is 60+55 = 115 mph. 345 miles/115 mph = 3 hours.
Check by plugging in. In 3 hours, Max travels 3 * 60 mph = 180 miles from the starting point. Min travels 3 * 55 mph = 165 miles in the other direction from the starting point. The total distance is 165 + 180 = 345 miles.
Answer: it will take 3 hours before the two are 345 miles apart.
Step-by-step explanation:
Let t represent the time it will take for them to be 345 miles apart. It means that after t hours, they would have covered 345 miles.
Distance = speed × time
Mr. Max is traveling at 60 mph. This means that the distance travelled by Mr Max in t hours is 60t
Mr. Min is traveling at 55 mph. This means that the distance travelled by Mr Min in t hours is 55t.
Since the total distance covered is 345 miles, it means that
60t + 55t = 345
115t = 345
t = 345/115
t = 3
