Answer:
360 miles
Step-by-step explanation:
When the second car catches up with the first car they will have travelled the same distance which we call x miles.
Speed = distance / time
For first car 60 = x / t where t = time taken
giving x = 60t
for second car 90 = x / (t - 2)
giving x = 90t - 180
So equating these 2 equations
60t = 90t - 180
30t = 180
t = 6 hours
So x the distance = 60t = 360 miles answer
Steps to solve:
(-5q^2 + 6q + 7) - (-q^2 + 4q)
~Distribute the left side
-5q^2 + 6q + 7 + q^2 - 4q
~Combine like terms
-4q^2 + 2q + 7
Best of Luck!
The distance is (3,4)
Simply subtract the x and y functions.
13 - 10 = 3
5 - 1 = 4
There are 0.453592 kilograms in 1 pound.
Multiply 13 by 0.453592 and get 5.8967
Now 0.0283495 kilograms in one ounce.
Multiply 7 by 0.0283495 and get 0.198447.
Now add them and get 6.095147
