Answer 1

Answer:

The difference between 1.30 hours and I hour 30 minutes is 12 minutes.

To find:

The difference between 1.30 hours and I hour 30 minutes.

Solution:

1 hour = 60 minutes  

1 minute = 60 seconds

1 hour and 30 minutes = 60 min + 30 min = 90 minutes in total

1.30 hours = 1 hour + 0.3 hour

0.3 hour =  ${\frac{3}{10}}^{th}$hour.

1 hour = 60 minutes

${\frac{3}{10}}^{th}$  hour  =$\frac{3}{10} \times$  60 = 18 minutes.

1.30 hours = 60 min + 18 min = 78 min.

Result:

The difference between 1.30 hours and I hour 30 minutes is 12 minutes.
