The answer is option B. In the distributive property you need to multiply the constant that is outside of the parenthesis, with the terms that are inside :)
Answer: 1h and 25min
To find how long you can drive in a minute we do 48 divided by 32 = 1.5. So it takes 1 min to drive 1.5km
Then we 146 divided by 1.5 = 97 and a third to find out how long it takes to drive 146km.
Then we convert it to hours to get 1h and 57min.
Then we - 32 because we already drove 32min. 1h and 57min - 32 = 1h and 25min

Step-by-step explanation:
<h3>
I will use the elimination method.</h3>
We want to make the X's the same:


Because the signs of the X's are the same we subtract the 2 equations to make:
(I put the second one on top of the 1st)

So:

Substitute y into either equation 1 or 2:
(I chose equation 1)



So:
