Question

multiply 5h 15 min 41s by 4​

Answer 1

Answer:

164

60 min.

20h

OR

to make 164 sec into min we have to minus 60 from it sucessively

164-60 = 104-60 = 44

so it would be 2 min. 44 sec.

60 +2= 62 min

to convert it into hour we have to do the same

62-60 =2

so it would be 1 hour 1 min

20 +1 =21 hours

so our ans. is 21 hours 2 min . and 44 sec.
