=-2(5)+1
=-10+1
= -9

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
