Question

The average of 1 hour 25minutes 2 hour 40minutes 3 hour 35 minutes and 4 hour is

Answer 1

ANSWER

AVERAGE WILL BE      2 HOUR 55 MINUTE

Step-by-step explanation:

FOR CALCULATING AVERAGE WE NEED TO CONVERT UNIT IN A SINGLE FORM.

WE WILL CONVERT HOUR IN MUNUTE

so               1 HOUR 25 MINUTE =   1 x 60 minute + 25 minute = 85 Minute

                 2 Hour 40 Minute     =   2 x 60 minute + 40 minute = 160 minute

                 3 Hour 35 Minute     = 3 x 60 minute + 35 minute    = 215 minute

                 4 Hour                        = 4 x 60 minute                          = 240 minute

for calculating average we ADD all the term and divide with No. of Term

           so,               Average  = (85 + 160 + 215 + 240) / 4

                                                 = 175 minute.

Now we know 60 minute = 1 hour

                                            so we can write      175 = (120 + 55) minute

so we have ans                 2 Hour 55 minute
