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 = [tex]\frac{60}{40}[/tex]
= 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.
90 minutes
Further explanation
Given:
- Rene is going to the lake to visit some friends.
- The lake is 60 miles away.
- Rene is driving at 40 miles per hour the entire time.
Question:
How long will it take her to get to the lake?
The Process:
We face a basic problem that connects distance, speed, and time. To solve this, we will use the formula:
[tex]\boxed{ \ Distance = Speed \times Time \ }[/tex]
Because we will find out how long to get to the lake, the formula is rewritten as follows:
[tex]\boxed{ \ Time = \frac{Distance}{Speed} \ }[/tex]
Let us calculate now.
[tex]\boxed{ \ Time = \frac{60 \ miles}{40 \ miles \ per \ hour} \ }[/tex]
[tex]\boxed{ \ Time = \frac{3}{2} \ or \ 1.5 \ hour \ }[/tex]
Therefore the time needed is 1.5 hours which we convert into minutes. i.e., [tex]\boxed{ \ 1.5 \ hours \times 60 \ \frac{minutes}{hour} \ }[/tex]
Thus she will take 90 minutes to get the lake.
