Maria and her friends went on a bike ride. The start and end times are shown below how long did they Ride

Start time: 1:09
End time: 2:05

56 minutes

Step-by-step explanation:

For this problem, we need to understand that for each hour there are sixty minutes within that hour.  From here, we can use the properties of addition and subtraction to calculate the amount of time Maria and her friends rode their bikes.

If they started at 1:09 and they ended at 2:05, they nearly spent an hour riding their bikes.  Note that by adding 4 minutes to the stop time, we would have 2:09, meaning 1 hour had passed (2:09 - 1:09 == 1 hour ).

Using this information, we can simply subtract the 4 minutes we added from the 1 hour to determine the total time they rode their bikes.

1 hour = 60 minutes

60 minutes - 4 minutes = 56 minutes

Thus, Maria and her friends rode their bikes for 56 minutes.

Cheers.
