Question

16. A train travels at an average speed of 85 miles per hour. If a trip

from Sue's house to Kentucky will take at least 4 hours, what is the
minimum distance between Sue's house and Kentucky?

Answer 1

340 miles

Explanation:

From definition of speed, it's distance traveled per unit time

Speed=Distance/time

Making distance the subject

Distance=Speed* time

Substituting speed of 85 miles per hour and time of 4 hours

Distance=85*4=340 miles

Therefore, if the train maintains the same speed, the distance between Sue's house and Kentucky is approximately 340 miles
