Answer 2

Answer:

75 seconds

Step-by-step explanation:

We know that,

1 min=60 seconds            (i)

1/4 min=60X1/4 sec

           =15 seconds          (ii)

By (i) and (ii),

1 and 1/4 minute= 60 seconds + 15 seconds

                          =75 seconds

Hence,1 and one fourth minute is equal to 75 seconds.
