a) Graham drove 31.75 miles in one hour.
My Work/Reasoning:
To find how much Graham drove in 1 hour, you divide the distance by time. 42 1/3 / 1 1/3
Then you convert the mixed fractions into improper fractions. 127/3 / 4/3
Finally, you solve the equation and learn that Graham drove 31.75 miles in one hour.
b) 4/127 hours
My Work/Reasoning:
In this case, you reverse the equation from (a). 1 1/3 / 42 1/3
Then you convert the mixed fractions into improper factions. 4/3 / 127/3
Finally, you solve the equation and learn that Graham takes 4/127 hours to drive one mile.
