Question 125330
For each, {{{d = r*t}}}
For each {{{t = 2}}}hrs
For the 1st plane, {{{r = 150}}} mi/hr
For the 2nd plane, {{{r = 200}}} mi/hr
{{{d[1] = 150*2}}}
{{{d[1] = 300}}} mi
{{{d[2] = 200*2}}}
{{{d[2] = 400}}} mi
They traveled apart at right angles to eachother, so
their distance apart is {{{d = sqrt((300)^2 + (400)^2)}}}
{{{d = sqrt(9*10^4 + 16*10^4)}}}
{{{d = sqrt(10^4(9 + 16))}}}
{{{d = 10^2*sqrt(25)}}}
{{{d = 500}}}mi answer
