Answer:
5 :)
Step-by-step explanation:
The area is 93.5 and he can cut out 10
Answer:
8 1/3 meters
Step-by-step explanation:
set up a proportion of corresponding sides:
TE/AY = JT/DY
25/AY = 18/6
cross-multiply:
18AY = 150
AY = 150/18 which is 8 1/3
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
