#### Calculator

1. enter the distance in miles
2. the speed in kilometres per hour

#### Results

1. the distance in miles converted to kilometres
2. the kilometres per hour converted to miles per hour
3. the time in decimal hours
4. the time in hour, minute, and second format

##### Formula
```time = distance ÷ speed
```
##### Conversions
```one one mile (mi) = 1.609344 kilometres (km)
one kilometre (km) = 0.621371192237334 miles (mi)
one mile per hour (mi/hr) = 1.609344 kilometres per hour (km/hr)
```
##### Example Calculation
`How long will it take to drive 120 miles at a speed of 70 kilometres per hour?`
`First convert 120 miles to kilometres;`
`120 * 1.609344 = 193.12`
`120 miles equals 193.12 kilometres`

`Divide the distance of  193.12 kilometres by the speed of 70 kilometres per hour to get the time in hours;`
`193.12 ÷ 70 =  2.758875`
```It will take 2.758875 hours to travel the 120 miles at a speed of 70 kilometres per hour.
2 hr - 45 min - 32 sec```
