The distance a train travels between 2 cities is 540 miles. The train travels at a speed of 80 miles per hour. Matt set up these
rates to find the time it took the train to travel between the 2 cities. 80 miles
1 hour
= ? hours
540 miles
What was Matt’s error?
The first rate should be written as 80 hours to 1 mile.
The second rate should be written as a rate of distance to time.
The first rate should compare miles to miles.
Matt did not make an error.
The answer is d. since the sock with a hole was returned, the probability of getting a black sock is out of 3 out of 9 because there are 3 black socks and 9 socks total. hope this helps!
