A car drives for 3 and three quarters hours, how long is this in minutes?”

We will do this in three steps:

**Step 1: **Convert the full hours into minutes

3 hours = 3\times60 minutes = 180minutes

**Tip: **Multiply by 6 and put a 0 on the end.

3\times6 = 18

3 hours = 18** 0** minutes

**Step 2: **Convert the extra bit to minutes

Three quarters of an hour = 45 minutes

**Step 3:** Add the minutes from **Step 1** and **Step 2 **together

180 minutes + 45 minutes = 225 minutes
