Q.no 26 ... PLZ ans fast​

Answer 1

Answer:

14 minutes

Step-by-step explanation:

Let the minute hand is at t.

Time needed by minute hand to show = 60 -t

According to the question,

=> 60 - t = (t^2/4) - 3

=> 60 - t =( t^2 - 12)/4

=> 4(60 - t) = t^2 - 12

=> 240 - 4t = t^2 - 12

=> t^2 +4t - 252 = 0

=> t^2 + 18t - 14t - 252 = 0

=> t(t + 18) - 14(t + 18) = 0

=> t = 14,-18{Time cannot be negative]

=> t = 14

Hence, the time is 14 minutes.
