Answer:
36
Step-by-step explanation:
12 x 3 = 36
Answer:
174 feet squared
Step-by-step explanation:
The figure is composed of a rectangle and a right triangle
Therefore,
Area of the composite figure = area of the rectangle + area of the right triangle
= (L*W) + (½*b*h)
L = 18 ft
W = 9 ft
b = 18 - (6 + 6) = 6 ft
h = 4 ft
Plug in the values into the equation
Area of the composite figure = (18*9) + (½*6*4)
= 162 + 12
= 174 ft²
Solution:
At 5:30 PM the distance between the train will be 621 miles.
Explanation:
We have been given that one train goes north and other train gores south. It means they are moving in opposite direction.
When two body moving in opposite directions then the relative velocity is the sum of their individual velocities.
Therefore, the relative speed is given by

Now, the distance between the train is 621 miles. Hence, using the relation between speed, time and distance, we have

Thus, at 5:30 PM the distance between the train will be 621 miles.
