Question 353200
The car and truck each have an equation
For car:
{{{d = r*t}}}
{{{d = 55*4}}}
{{{d = 220}}} mi
For truck:
{{{d = r*t}}}
{{{d = 50*4}}}
{{{d = 200}}} mi
By the pythagorean theorem:
distance apart = {{{sqrt(220^2 + 200^2)}}}
{{{sqrt(48400 + 40000)}}}
{{{sqrt(88400) = 297.321}}}
They are 297.321 mi apart after 4 hrs
