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:
To calculate your average speed, you need time in the decimal format because calculating $\rm{264}/{3h40m}$ is not a straightforward operation.
Let's see how you convert clock time to decimal:

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

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

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

Add this to the hours to convert time in decimal format: $3 + 0.667 = 3.667 \text{ hrs}$.
🔎 Now, you may insert this value into the average speed formula. You can verify your result using our speed calculator.
