a) Kushal is training for a 400 m race. He ran five practice races so far. The timetaken by him to complete each race (in seconds) was 118, 112, 138, 125, and118. Kushal's median time becomes 121 seconds after 6 races. In how manyseconds does he complete his sixth race? Explain your answer.​

Answer 1

Answer:

Given values are 112, 118, 118, 125, 138 and another value X

Since we have 6 values so Median should be (118+X)/2=121

So, 59+0.5X=121

0.5X=121-59

0.5X=62

X=62/0.5

X=124
