For this case we have the following definition:
d = v * t
Where,
d: distance
v: speed
t: time
Clearing the time we have:
t = d / v
Substituting values:
t = 1505/420
t = 3,583 hours
Answer:
Flight time hours:
t = 3,583 hours
Answer: There were 89 retail stores in 1997.
Step-by-step explanation:
Hi, to answer this question, first, we have to calculate the number of years since 1990(x).
1997-1990 = 7 years
Now, we simply substitute x=7 (years) in the equation given
y=11x+12
y=11(7)+12
y=77+12
y = 89 retail stores
There were 89 retail stores in 1997.
