2) 62751 : 1000 = 62,751 ( км/час) 
Ответ 63 км/час

Answer 2

Conversion of Speed from Miles per Hour to Kilometers per Hour

To convert the speed from miles per hour (mph) to kilometers per hour (km/h), we can use the conversion factor that 1 mile is equal to 1609 meters.

Given: - Speed indicated by the speedometer: 39 miles per hour (mph)

To convert this speed to kilometers per hour (km/h), we can use the following calculation:

1. Convert miles to meters: - 39 miles * 1609 meters/mile = 62751 meters

2. Convert meters to kilometers: - 62751 meters / 1000 = 62.751 kilometers

3. Convert hours to seconds: - 1 hour = 3600 seconds

4. Calculate the speed in kilometers per hour: - 62.751 kilometers / (1 hour / 3600 seconds) = 62.751 km/h

Rounding to the nearest whole number, the speed of the car in kilometers per hour is approximately 63 km/h.
