Question 359041
Calculate the time it takes both ways.
.
.
Rate*Time=Distance
{{{R*t=D}}}
{{{t=D/R}}}
.
.
{{{t[1]=330/60=5.5}}}hrs
{{{t[2]=330/40=8.25}}}hrs
.
.
Average speed is total distance divided by total time,
{{{V[ave] =(330+330)/(5.5+8.25)}}}
{{{V[ave]=660/13.75}}}
{{{highlight(V[ave]=48)}}}mph
