Question 220543
Recall that the distance 'D' is related to the rate/speed 'r' and time 't' by the formula: {{{D=rt}}} (ie multiply the speed by the time to get the distance traveled).



{{{D=rt}}}



{{{7.6=3t}}} Plug in {{{D=7.6}}} (the given distance) and {{{r=3}}} (the given speed)



Now the goal is to simply solve for 't':



{{{7.6/3=t}}} Divide both sides by 3 to isolate 't'.



{{{2.533=t}}} Divide 7.6 into 3 to get 2.533 (this is approximate).



{{{t=2.533}}} Rearrange the equation.



So the solution is {{{t=2.533}}} which means that it takes about 2.5 hours to walk 7.6 miles.
