Converting analogue to digital clock

LI. To convert between analogue and digital clocks. This week for maths we had to create a DLO and write our typical day. We had also had to write the time we do those things and the minutes it takes. If it is over an hour we keep it like that. For example- 90min and convert it to 1h and 30min. To work this out do this. You know that 60min is 1h. So if you have a total of 100min you get 60min from the 100min and you have 1h. You should know that you should have 40 left. So then you have your total which is- 1h 40min.
