Answer:
Speed = 23809.52 cm/min
Step-by-step explanation:
Given : A car travels at constant speed for 7 days and covers 1500 miles.
To find : What is the speed in centimeters/minute
Solution : Formula to find speed is
Distance traveled = 1500 miles and time taken = 7 days
Now, we have to convert miles into centimeter and days into minutes.
1 day = 24 hours
1 hour= 60 minute
24 hr= 24×60 minute
1 day = 24×60 minute
7 days = 7×24×60 minute = 10,080 minute
Now, 1 mile = 8/5 km = 1.6 km
1 km= 100000 cm
1.6 km = 1.6 × 100000 cm
1 mile = 1.6 × 100000 cm
1500 miles = 1500×1.6 × 100000 cm = 240,000,000 cm
Put back the values into speed
Therefore, speed = 23809.52 cm/min
I have attached the image showing the location of the three schools.
Answer:
Should be built at the centroid of the triangle formed by points A, B and C.
Step-by-step explanation:
From the attached image, we see that if we join the 3 points by a straight line, they will form a triangle.
Now, to get a location that will be roughly the same distance from all 3 schools, it means a point that is equal to each of 3 vertex of the triangle.
The point that is equal to each vertex of a triangle is known as "Centroid".
Now, to find this centroid, we will add up the (x, y) coordinates of the 3 vertex and divide by 3.
For example;let's assume ;A has a coordinate of (x1, y1) ; B has a coordinate of (x2, y2) ; C has a coordinate of (x3, y3).
The coordinates of the centroid will be;
[(x1 + x2 + x3)/3], [(y1 + y2 + y3)/3]
