500 miles into kilometers (write your answer whole number)
500 mi = km

Explanation:

Question 1

Step1: Unit conversion factor

We know that \(1\) kilometer \( = 0.621371\) miles.

Step2: Convert \(140\) km/hr to mi/hr

Multiply \(140\) by the conversion factor \(0.621371\). So, \(140\times0.621371 = 86.99194\approx87\) mi/hr.

Question 2

Step1: Unit conversion factor

We know that \(1\) mile \(= 1.60934\) kilometers.

Step2: Convert \(500\) miles to kilometers

Multiply \(500\) by the conversion factor \(1.60934\). So, \(500\times1.60934 = 804.67\approx805\) km.

Answer:

Question 1: \(87\) mi/hr
Question 2: \(805\) km
