90 minutes
<u>Given:</u>
<u>Question:</u>
How long will it take her to get to the lake?
<u>The Process:</u>
We face a basic problem that connects distance, speed, and time. To solve this, we will use the formula:
Because we will find out how long to get to the lake, the formula is rewritten as follows:
Let us calculate now.
Therefore the time needed is 1.5 hours which we convert into minutes. i.e.,
Thus she will take 90 minutes to get the lake.
Answer:
Option C, 90 minutes.
Step-by-step explanation:
Rene is going to the lake to visit some friend.
Lake is 60 miles away.
Rene is driving at 40 miles = 1 hour
she will take time to get to the lake =
= 1.5 hours
1 hour = 60 minutes
1.5 hour = 60 × 1.5 = 90 minutes
It will take Rene 90 minutes to get to the lake.
w = 3(2a + b) - 4
w = 6a + 3b - 4
a = (w - 3b + 4) / 6
