Well, the answer quite simple ....there are 4! ways to arrange these numbers...and as 4! = 4*3*2*1 = 24
hence 24 is the correct answer....
u can also remember it by theorem of multiplication as.....in first place (I.e. first code can be any no. out of 4,5,2&7 ....so 4*.....
as first place is acquired by a certain no. that leaves three no. to fill third place and when third place I'd occupied it leaves 2 numbers to fill second place and lastly only one no. to fill the last place .....so it's result will be like 4*3*2*1.
I know this is pretty much confusing ....but still I tried my best....
if anything troubles u here feel free to ask me

Answer:
Adrian rode his scooter for a total of 70 minutes, or an hour and ten minutes.
Step-by-step explanation:
There are 60 minutes in an hour, so if Adrian started riding his scooter at 7:00AM, to get to 8:10AM he needs to add 70. Again, since there are 60 minutes in an hour, 70 minutes converts to one hour and 10 minutes. Adrian rode his scooter for 70 minutes, or an hour and ten minutes.
7:00 + :70 = 8:10
