Question 194336
if a person can run A miles in x hours, how long will it take the person to run B miles at the same rate?
:
Find the rate of speed if you run A mi in x hrs:
rate = {{{A/x}}}
:
Find the time to run B mi at a rate of {{{A/x}}}
Time  = {{{B/(A/x)}}}
invert the dividing fraction and multiply:
Time = B * {{{x/A}}} = {{{(Bx)/A}}}
