1. ***In 1987, Art Boileau won the Los Angeles Marathon, 26 mi and 385 yds, in 2 h, 13 min, and 9 s. At the 21- mi marker, Boileau had a 2.50-min. lead on the second place winner, who later crossed the finish line 30 s after Boileau. Assume that Boileau maintained one constant average speed during the race and that both runners had been running at the same speed when Boileau passed the 21-mi marker. Find the average acceleration (in m/s?) that the second place contestant had during the remaining part of the race after Boileau passed the 21-mi marker. (1 mile is 5280 feet, 1 yard is 3 feet, 1 foot is 12 inches, and 1 inch is 2.54 cm, or 0.0254 m)

Question
100%

please just send me the paper solution and don't give me the wrong answer and solutions please and use 9.81m/s^2 if needed not 9.81 and only use the formula that is giving and make sure the writing is clear for me

 

please ASAP faster I really need it

Assume that Boileau maintained one constant average speed during the race and that both runners had been running at the same speed when Boileau passed the 21-mi marker. Find the average acceleration (in m/s²) that the second place contestant had during the remaining part of the race after Boileau passed the 21-mi marker.
