Question 989936
Find the time for both distances.
{{{t[1]=9.3/82.5=0.1127}}}{{{hr}}}
{{{t[2]=6.7/52.8=0.1269}}}{{{hr}}}
Total distance traveled is,
{{{d=9.3+6.7=16}}}{{{km/hr}}}
Total time to travel is,
{{{t=0.1127+0.1269=0.2396}}}{{{hr}}}
So the average speed is,
{{{S[ave]=16/0.2396=66.8}}} {{{kph}}}
