Answer:
Since speed is given in terms of "hours" we must convert 9 minutes to hours:
9 minutes = 9/60 hours = 3/20 hours
.
Let x = time (hours) it takes car to pass the truck
then
60(x + 3/20) = 69x
multiplying both sides by 20:
60(20x + 3) = 1380x
1200x + 180 = 1380x
180 = 180x
1 hour = x

Answer:
10.5625 is the answer I got.
Step-by-step explanation:
I used the process PEMDAS for this equation.
(6.5÷2)^2
6.5÷2= 3.25^2
Now you bring down the new quotient and multiply it by itself.
3.25 x 3.25= 10.5625
It would actually be -14 because 5+4-2=7 and if you multiply 7 by -2 you get -14
