Question 946117


if a car travel {{{(3/8)}}} of a mile in {{{17.564}}} seconds, then
{{{(3/8)/17.564=0.375/17.564=0.0214(mil/s)}}} (miles in one second)

since {{{1second=0.0002778hours}}} if a car travel {{{0.0214(mil/s)}}} , then  

speed of the car will be {{{(0.0214/0.0002778)(mil/h)=77.04(mil/h)}}}
