Answer:

y = 39/2 = 19.5

Step-by-step explanation:

When x is multiplied by 2 from 13 to 26, y will be multiplied by the inverse of that:

y = (1/2)(39) = 39/2 = 19.5

SashulF [63]

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

$\text{Average speed }=\frac{2xy}{x+y}\\\\=\frac{2\times 10\times 30}{10+30}\\\\=\frac{600}{40}\\\\=15$

Therefore, average speed is 15 mph
