Question

Answer the question given below!!!

Answer 1

walking is t

running is h

the equation is t+h=250

now need to find two solutions

 first solution

t=100

100+h=250

h=250-100

h =150

second solution

t =150

150+h+250

h=250-150

h =100

use h as x axis and t as y axis

two solutions are

[150,100],[100,150]

mark this point in graph

where scale x and y axis is 10 cm per unit
