1. pizza paradise delivers pizza in the local neighborhood using bicycles. the bike delivery person, tommy, uses a bike whose wheels have a radius of 13 in. tommy’s average biking speed is 15 mph. how many minutes would it take for tommy to deliver a pizza to a house that is 4 mi away, and how many revolutions of his bike wheels would this take? (a revolution is one full wheel turn.) use 3.14 to approximate pi. round to the nearest whole number.

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.
