lin ran 23/4 in 2/5 of a hour.noah ran 82/3 in 4/3 of an hour.how long would it take lin and noah to run 1 mile at that rate

Answer 1

L ran 23/4 in 2/5 hour. that's 5(23/4) per 2hours = 115/2= 57.5 per hour, probably not mph, maybe 5.75 miles per hour, above average walking speed. One mile would be done in 1/5.75 = .174 hours= about 10.4 minutes

Noah does 82/3 in 4/3. That's 82/3 in 4/3 of an hour, 1 1/3 hours. In one hour, Noah does 3/4 of 82/3 = 82/4 = 20.5 miles. 20.5 miles per hour is better than the world record marathoner. or the 4 minute mile

60/20.5 = less than 3 minutes for 1 mile, About 2.9 minutes
