Answer:
125 blue vehicles
Step-by-step explanation:
In this question, we are going to estimate the number of vehicles of a specific color given that there are some numbers of both vehicle models present in a sample.
Now to solve this question, we are going to treat the sample numbers as a ratio.
The ratio here is thus 7 black to 5 blue I.e 7:5
We have 300 vehicles, we now want to estimate the number of blue vehicles present.
From the sample ratio, there are a total of 12 vehicles
Now the total number of blue vehicles would be 5/12 * 300 = 125
There are 125 blue vehicles

Answer:
Step-by-step explanation:
What you are trying to do is a nice way to solve this problem. Without knowing any physics, you are using what math you know to get the answer. You are actually very close to being correct, and you are right. You do have to divide by 60.
Here's why and it is the one bit of physics you have to know.
The speed is km/hour. That word hour is the culprit. Your time is in minutes and you have to get it into hours. In physics, the units have to be consistent.
So ...
b1 = 19 minutes which is 19 min [1 hour / 60 minutes] = 19/60 = 0.31667 hour
b2 = 26 minutes which is 26 min [ 1 hour/60 minutes] = 26/60 = 0.4333 hour
h = 40 km/hour
Area = (0.31667 hour + 0.4333 hour)*40 km/hour /2
Area = 0.75 hour * 40 km/hr //2
Area = 15 km
