Question

Susan gets in her car in Boston and drives toward New York City, averaging fifty miles per hour. Twenty minutes later, Ellen gets in her car in New York City and starts driving toward Boston, averaging sixty miles per hour. Both women take the same route, which extends a total of 220 miles between the two cities. Which car is nearer to Boston when they meet?

Answer 1

Step-by-step 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
