An airplane on autopilot took 7 hours to travel 5,005 kilometers. What is the unit rate for kilometers per hour? and explain your answer plz

The answer is 715. To get the answer, you just divide 5005 by 7 since the rate of speed is steady.

step-by-step explan mxfcg'k; uafwgzfgjhklhgation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
