The distances between some planets are given below. Planet Q is 3.6 x 10 to the power of 6 km from planet P.
Planet R is 1.6 x 10 to the power of 7 km from planet P.

Work out the shortest distance between
planet Q and planet R.
Give your answer in standard form.

The bed of the truck is a rectangle, 4-ft wide and 8-ft long.

The diagonal of the rectangle is

                                 √ (4² + 8²)

                             =  √ (16 + 64)

                             =  √ (80)

                             =  8.9442... feet 

                        8.9442... feet =  8 feett  11.33 inches

Rounded to the nearest inch:    8 ft  11 in .
