Question

Multiply: 1h 15 min 20 sec by 4.​

Answer 1

Answer:

5 h 1 min 20 sec

Step by step explanation:

  1 h 15 min 20 sec

×₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋4

4 h 60 min 80 sec

Now, 60 sec = 1 min

         80 sec = 1 min 20 sec

so we will add 1 to 60 mins thus giving us 61 mins

now again, 60 min = 1 h

                   61 min = 1 h 1 min

so we will add 1 to 4 h thus giving us 5 h

Therefore final answer will be 5 h 1 min 20 sec
