Scarecrow and the Tin Man are walking in a field toward Emerald City! When they start walking, Scarecrow is 25 meters away and Tin Man is 40 meters away. Scarecrow is walking at a rate of 5 meters per minute and Tin Man is walking at a rate of 10 meters per minute. After how many minutes will Scarecrow and Tin Man be the same distance from Emerald City? What are two equations to solve this problem?

Step-by-step explanation:

(x+y+z)²=x²+y²+z²+2(xy+yz+zx)

(14)²=x²+y²+z²+2.3

196=x²+y²+z²=6

x²+y²+z²=190

x³+y³+z³-3xyz

=(x+y+z)(x²+y²+z²-xy-zx-zx)

=14(190-3)

=14×187

=2618

Put the value of r = 3 in equation, we get.
