Answer:
The rocket has a faster unit rate and is [tex]219\ km/h[/tex] much faster than the penny
Step-by-step explanation:
Find the unit rate of each object and the compare the results
step 1
Find the unit rate per hour of the rocket
To find the unit rate divide the total distance by the time
Let
d -----> the distance in km
t -----> the time in hours
we have
[tex]d=208\ km[/tex]
[tex]t=50/60=5/6\ h[/tex]
Find the unit rate
[tex]208/(5/6)=208*6/5=249.6\ km/h[/tex]
step 2
Find the unit rate per hour of the penny
To find the unit rate divide the total distance by the time
Let
d -----> the distance in km
t -----> the time in hours
we have
[tex]d=153\ km[/tex]
[tex]t=5\ h[/tex]
Find the unit rate
[tex]153/5=30.6\ km/h[/tex]
step 3
Compare the unit rates
The units rate of rocket is [tex]249.6\ km/h[/tex]
The unit rate of penny is [tex]30.6\ km/h[/tex]
Find the difference
[tex]249.6-30.6=219\ km/h[/tex]
therefore
The rocket has a faster unit rate and is [tex]219\ km/h[/tex] much faster than the penny
