we need to compare two quantities which have different units. First, we will convert them in same unit of time. Note that we can convert them into either hour or minute, Any third unit like second, Milisecond etc. will I will also work. But for convenience, we will convert them into minutes.

1 hour = 60 minutes

4 hour = 60 minutes × 4 = 240 minutes
