Question

A person has to cover 360 km distance. If he increases his speed by 10 km/hr he reaches 3 hours earlier. Find his initial speed.

Answer 1

I DON'T KNOW I DON'T KNOW I DON'T KNOW I DON'T KNOW I DON'T KNOW I DON'T KNOW I DON'T KNOW I DON'T KNOW I DON'T KNOW

Answer 2

Answer:

360/x -360/x+10 =3

3(x^2 +10x) =360x +3600 -360x

x^2+10x -1200

x^2 +40x -30x -1200

x(x+40) -30(x+40)

x=30 neglect negative value

initial speed is 30
