Question

Lessons are 55 mins long, a history lesson ends at 3:30 pm at what time does the lesson start

Answer 1

2:35 pm

If an hour is 60 minutes, what we know is that 30 minutes is half. However, we must subtract 55 from 30 (In time)

To make this easier, subtract 55 by actual 30, and split 55 into 2 parts, the result of subtraction, and the other value, 30

`55-30=25`

Now, subtract.

`3:30 - 30 = 3:00`

`3:00-25=35`

If this is the case, the lesson must have started at 2:35 pm
