Question 907348
Distance = Velocity(Or Speed) x Time
{{{D = V * T}}}
Given: {{{V = 63.5km/hr}}} & {{{D = 889km}}}
----------------------
{{{889km = (63.5km/1hr)*T}}}
Multiply both sides by (1hr/63.5km)
{{{(1hr/63.5km)*889km = (1hr/63.5km)*(63.5km/1hr)*T}}}
Notice that certain terms now cancel out.
{{{(1hr/63.5cross(km))*889cross(km) = cross((1hr/63.5km))*cross((63.5km/1hr))*T}}}
Simplify
{{{(889hr/63.5) = T}}}
Simplify
{{{highlight(14hr = T)}}}
