Question

The distance between some planets are given below.
Planet Q is 3.5× 10^6 km from planet P
Planet R is 1.2 × 10^7 km from planet P
Work out the shortest distance between planet Q and planet R.
Give you answer in standard form.

Answer 1

Answer:

1.25×10^7

Step-by-step explanation:

This is just a basic problem which can be solved by using Pythogorus theorem.

Here,

Distance PQ and QR are either base or perpendiculars in a right angled triangle.

Just plug in these values in the given formula,

h = sqrt(PQ^2+QR^2)

h = sqrt((3.5×10^6)^2+(1.2×10^7)^2)

h = 1.25×10^7
