First we need to turn Aouita's time for the race into seconds. There are
60 seconds in a minute, so 7 minutes and 29.45 seconds is (7 x 60) +
29.45 = 449.45. He ran 3000 meters in that time, so his average speed
was 3000 meters divided by 449.45 seconds. 3000 / 449.45 = 6.67 m/s. So,
on average, he covered 6.67 meters (more than 21 feet!) during each
second of the race.

Hope it helps!
i don't know what symbol ya'll use for wavelength so i just put the word instead.We use the greek symbol lambda.So just plug in everything you know.
wavelength=4.257×10^-7x10^-2 and
v=speed of light = 3×10^8
So you should get f= 7.04 ×10^15Hz
