Question 326760
Rate*Time=Distance
.
.
.
In that two hours, the first jet moved 360 km.
Find the distance for each plane when they meet {{{D1=D2=D}}}.
1.{{{D=D1=180*t+360}}}
2.{{{D=D2=900*t}}}
From eq. 2, 
{{{t=D/900}}}
Substitute into eq. 1,
{{{D=180(D/900)+360}}}
{{{D=0.2D+360}}}
{{{0.8D=360}}}
{{{D=360/0.8}}}
{{{highlight(D=450)}}}km
