# Average Speed in Miles per Hour

Calculate the average speed from a distance in miles and the time it took to complete the distance.

### Average Speed from Distance and Time

Distance Traveled in Miles mi
Time hrs mins secs
Decimal Rounding #

#### Results:

 Miles per Hour mi/hr Kilometres per Hour km/hr

#### Calculation

1. enter the distance in miles
2. time of trip in hours, minutes and seconds
3. number of digits after the decimal point for the results

#### Result

1. the average speed in miles per hour
2. the average speed kilometres per hour

### Formula

`average speed = distance/time`

### Example Calculation

```Step one: Change the 34 minutes into an hourly value.

one minute = 0.01667
```
`0.01666667 * 34 = 0.57 (rounded to two digits)`
```time of trip in hours = 4 +  0.57 = 4.57 hrs

```
`Step two: divide the distance traveled by the amount of time.`
`330 ÷ 4.57 = 72.2 `
`The average speed  72.2 miles per hour.`

### Conversions

```one hour = 60 minutes
one minute = 0.01666666666666666666666666666667 hours
one mile (mi) = 1.609344 kilometres (km)
