The train travel 20 kilometers in the southward direction to reach its original location.
Step-by-step explanation:
The given is,
First train travels east for 50 kilometers, then
Turns north and travels for 22 kilometers
It goes west for 50 kilometers
Step:1
Let, A - Distance of train travels from its starting point in Eastern direction at pq point
B - Distance train travels in northward direction at qr point
C - Distance of train travels in western direction at rs point
D - Distance of train travels in southward direction to reach its starting location at sp point
Step:2
Refer the attachment,
Distance of travel in northward direction and distance of travel in southward direction are equal.
qr = sp.............. (1) ( ∵ Eqn (1) from the Diagram)
20 km = 20 km
sp = 20 km
Result:
So, the distance of train travel to reach its original location in southward direction is 20 km.
Answer:
Step-by-step explanation:
(a + b)² = a² + 2ab +b²
a = y & b = 10
(y + 10)² = y² + 2 *y*10 + (10)²
= y² + 20y + 100
To do this, divide 15 by 120. You get 0.125 Then turn the decimal into a percent. You do this by moving the decimal point to places to the RIGHT. You get 12.5% as your answer.
