Answer:
2
Step-by-step explanation:
A midpoint divides a segment in two equal segments
DB = 3t
AB = 6t
BE = 4t
BC = 8t
8t + 6t + 7t + 6 = 48
21t = 42
t = 2
The answer is D
Solve for " t " by simplifying both sides of the inequality, then Isolating the variable.

Let x be the length of the train.
On the basis of the observer;
Speed of the train = x/6
On the basis of the bridge;
Total distance covered by any point of the train= 350+x
Speed = (350+x)/20
Equating the two expressions of speed;
x/6 = (350+x)/20
20(x) = 6(350+x)
20x = 2100+6x
(20-6)x = 2100
14x = 2100
x= 2100/14 = 150 m
Speed = x/6 = (350+x)/20 = 150/6 = 500/20 = 25 m/s.
Therefore,
Length of train = 150 m
Speed of train = 25 m/s
The area of lens is 3.14 square yards.
Step-by-step explanation:
Given,
Circumference of lens = 6.28 yards
Circumference = 2πr
Dividing both sides by 6.28
Area of lens = πr²
Area of lens = 
Area of lens = 3.14 square yards
The area of lens is 3.14 square yards.
