Answer 2

Answer:

Step-by-step explanation:

Pinky's school playground = 75+40×2= 230 (perimeter)

Jay's school playground = 90+30×2 = 240 (perimeter)

Both finished two rounds of the school playgrounds=

Pinky's jogging distance= 230×2=460 m

Jay's jogging distance = 240×2= 480 m

therefore, Jay jogged longer distance by pinky as=

                          480 > 460

Who jogged longer? =

480-460= 20

Jay jogged 20m more than Pinky.
