Answer:
average speed for the entire trip is 15 mph
Step-by-step explanation:
Let x be the uphill speed and y be the downhill speed.
We have been given that
Speed of Omar in uphill to reach gift store = x =10 mph
Speed of Omar in downhill to reach his home = y = 30 mph
We know the formula for average speed for the entire trip
![\text{Average speed }=\frac{2xy}{x+y}\\\\=\frac{2\times 10\times 30}{10+30}\\\\=\frac{600}{40}\\\\=15](https://tex.z-dn.net/?f=%5Ctext%7BAverage%20speed%20%7D%3D%5Cfrac%7B2xy%7D%7Bx%2By%7D%5C%5C%5C%5C%3D%5Cfrac%7B2%5Ctimes%2010%5Ctimes%2030%7D%7B10%2B30%7D%5C%5C%5C%5C%3D%5Cfrac%7B600%7D%7B40%7D%5C%5C%5C%5C%3D15)
Therefore, average speed is 15 mph
