Sove the following equation for r:$$\frac{60}{r}+\frac{24}{(r-4)}= 8$$$$\left\{r\to \frac{5}{2},r\to 12\right\} $$

anonymous · Answer

Let v be the$$\frac{60}{v}+\frac{24}{v-4}=8$$ speed travelled.  For the first part of the trip the time taken was 60/v .  For the second leg of the trip the time take was 24/(v-4).  The sum of these two is the total time of the trip, given as 8 hours. Solve for v.  v is the speed of the first part of the trip, and v-4 is the speed of the second part of the trip.
