Answer:

11 kg

Explanation:

Given weight in kg ∝ d² where d is the distance of the object from the center of the earth

We can write this as an equatio

w = (k/d²) where  is a constant

On the surface of the earth, d = 600, w = 80 so we get

80 = k/600² ==> k = 600² ( 80) =  600 x 600 x 80  (1)

At 1000 km altitude, the actual distance of the astronaut from the center of the earth is 1000 + 600 - 1600 km

So we get another equation w' = k/1600²

were w' is the weight of the astronaut at an altitude of 1000km

Using the value of k from (1) we get

w' = (600 x 600 x 80)/(1600 x 1600) = 11.25kg = 11 correct to the nearest kg
