118. Kushal's median time becomes 121 seconds after 6 races. In how many
seconds does he complete his sixth race? Explain your answer.​

Answer 1

Answer:

length of the race-400m

time taken for each race-118,112,138,125 and 118

median is 121 so , time taken during 6th race is

118+112+138+125+118+x/6=121

611+x/6=121

611+x=726

x=726-611

x=115
