Answer:

Explanation:

Susan = 50 miles per hour

Ellen = 60 miles per hour

Total miles to and from Newyork and Boston= 220 miles

In twenty minutes, Susan drives

50 miles = 60 minutes

1 minute= 50/60= 0.833 miles

20 minutes = 0.833×20=16.667 miles

Ellen is 60 miles per hour

Therefore she drives:

60 miles= 60 minutes

1 mile = 1 minute

In 1 hour 40 minutes Ellen would be 100 miles into getting to Boston and in 2 hours Susan would be 100 miles towards New York
