Answer:
<h2>16.666...%</h2>
Step-by-step explanation:
Let y be the first number
and x be the second number
then
y=x+20%x = (120/100)x
y=(120/100)x ⇔ x=(100/120)y
let‘s write x=(100/120)y in the form x=(p/100)y where p is a number to find
100/120=p/100 ⇔ p=(100×100)/120 = 83.333.....
then x = (83.333/100)y
since 83.333 = 100 - 16.666
then x = y - 16.666%y

Answer:
137.13km
Step-by-step explanation:
A right triangle is formed, where h + r = 2+ 4700= 4702 km is the hypotenuse, r = 4700km is one leg and d is the other leg. By Pythagorean theorem:
4702² = 4700² + d²
d² = 4702² - 4700²
d = √18,804
d = 137.13 km
