Answer:
The rocket has a faster unit rate and is 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
Find the unit rate
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
Find the unit rate
step 3
Compare the unit rates
The units rate of rocket is
The unit rate of penny is
Find the difference
therefore
The rocket has a faster unit rate and is much faster than the penny
