Need fast help on a algebra II question. Im basically done with the problem but need help on one last step?

Question

Have a test tomorrow so studying my butt off

so ill just put the problem right here: how long will it take to drive 325miles at 55miles per hour.

I know this should be very easy but im stuck at the way end rofl

so i did D=R*T

so 325= 55T

then divided 325/55= 5.9

so i have the answer 5.9 but how do i convert this into hours and minuts

i know the answer is 5 hours and ____ minutes but how do i convert my decimal of 5.9 into hours and minutes is what im dumbfounded on

Answer 1

.9 = 9/10

9/10 = x/60

so, minutes = (9*60)/10

Answer 2

5 hours and 54 minutes

Answer 3

I think it's 54 minutes.

The decimal of .9 is 9/10s of an hour. By multiplying 60 by .9 gives you 9/10s of an hour.

54 minutes.

You can think about it that 60 minutes divided by 10 (10 parts) is 6 minutes, so you subtract one 6 minute part.

Hope this helped! Good luck!

Answer 4

.9 * 60 = 54 minutes

5 hours 54 minutes.

Answer 5

use the cross multiply method:

1/60 = .9/x

=> 1 * x = .9 * 60  

=> x = .9 * 60

=> 54 mins.

there you go.

Answer 6

Let  t = mins in the hour.

so think:"How many mins are in this hour.?"

equation form:    ?t=.9 hour

you know there's 60 mins per hour.....   so it's   60min/1hour

so  0.9hour (60min/hour) = 54 min.

and your answer for the 0.9 hour is 54 min...

add that to the 5 hours, and you'll get

5.9 hours = 5 hours and 54 min.
