Starting at home, omar traveled uphill to the gift store for 30 minutes at just 10mph. he then travelled back home along the same path downhill at a speed of 30mph. what is his average speed for the entire trip to the gift store and back?

We know, Speed = Distance / time
Let, the distance = d
Time for first trip = d/10
Time for second trip = d/30

Total time = d/10 + d/30 = 4d/30

Now, Average speed = total distance / total time
s = 2d / 4d / 30
s = 2d*30 / 4d
s = 30/2
s = 15

In short, Your Answer would be: 15 mph

Hope this helps!

The answer is budget i believe. hope this but it’s self explanatory.
