Eric takes a train to his parent’s house 320 miles away.
If the trip takes 4 hours.
A train covers 320 miles in 4 hours.
The unit rate of train is number of miles cover in 1 hour.
Using formula:
[tex]Rate=\dfrac{distance}{time}[/tex]
where, distance = 320 miles
Time = 4 hours
[tex]Rate =\dfrac{320}{4}[/tex]
[tex]Rate = 80\text{ mph}[/tex]
Hence, The unit rate of train is 80 miles per hour.
