Decimal time conversion

Say it took you 3 hours and 40 minutes to travel 264 miles in a car. Your average speed is given by the formula:

speed=distancetime\rm speed = \frac{distance}{time}

To calculate your average speed, you need time in the decimal format because calculating 264/3h40m\rm{264}/{3h40m} is not a straightforward operation.

Let's see how you convert clock time to decimal:

  1. Divide seconds by 60 secs/min60 \text{ secs}/\text{min}. Your trip took 3 hrs 40 mins 0 secs: 0/60=0 mins0/60 = 0 \text{ mins}.

  2. Add this to the minutes to get minutes in decimal form: 40 mins+0=40 mins40 \text{ mins} + 0 = 40 \text{ mins}.

  3. Divide minutes by 60 mins/hr60 \text{ mins}/\text{hr}: 40/60=0.667 hrs40/60 = 0.667 \text{ hrs}.

  4. Add this to the hours to convert time in decimal format: 3+0.667=3.667 hrs3 + 0.667 = 3.667 \text{ hrs}.

🔎 Now, you may insert this value into the average speed formula. You can verify your result using our speed calculator.
