$\frac{1000}{x} +\frac{2500}{x-5}$

Step-by-step explanation:

Total time T = (distance 1)/ (speed 1) + (distance 2)/ ( speed 2)

Distance covered by the mountaineer = 1000 feet

Speed of climbing = x feet per hour

Time taken will be = $\frac{1000}{x}$

Additional distance covered by him = 5000 feet

Speed to cover this distance = 2x-10 or 2(x-5)

So, total time T = $\frac{1000}{x} +\frac{5000}{2(x-5)}$

T = $\frac{1000}{x} +\frac{2500}{x-5}$
