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.
There would be 1/8 of the pie left, you have to add 3/4 and 1/8 to find the total eaten and then subtract it by 8/8 (the total) which would give you your answer.
