It would take the car at least 8 minutes for it to pass the truck .
R=i/pt
i=16731.12-16100=631.12
R=631.12/16,100×1
R=0.0392*100=3.92%
Answer:
<u>Kathy drove the first 9 hours of the trip and Brian drove the last 3 hours.</u>
Step-by-step explanation:
Let's review the information given to us to answer the question correctly:
Total distance of the trip = 750 miles
Time of the trip = 12 hours
Speed of Kathy = 65 mph
Speed of Brian = 55 mph
2. For what length of the time did Kathy and Brian drive?
Let's solve the problem, this way:
x = Time in hours Kathy drove
12 - x = Time in hours Brian drove
Now, let's write our equation to solve for x:
65x + 55 (12 - x) = 750
65x + 660 - 55x = 750
10x = 750 - 660
10x = 90
x = 90/10
x = 9 ⇒ 12 - x = 3
<u>Kathy drove the first 9 hours of the trip and Brian drove the last 3 hours.</u>
Answer:
$28.00
Step-by-step explanation:
You start with 35.00.
Now 10% of this is 3.5.
Multiply by 2 because it's 20%.
You get 7, so 7 is 20% of 35.00.
35.00 minus 7 is 28.00.
The pair of pants will be 28.00 dollars!
