Question

convert the value from meters/second to kilometers/hour. one kilometer is equal to 1,000 meters, 3,600 seconds. type the correct answer in the box. 105 m/s = km/h

Explanation:

Step1: Convert meters to kilometers

Since 1 km = 1000 m, 1 m = $\frac{1}{1000}$ km.

Step2: Convert seconds to hours

Since 1 hour = 3600 s, 1 s=$\frac{1}{3600}$ h.

Step3: Perform the unit - conversion

$105\frac{m}{s}=105\times\frac{\frac{1}{1000}\text{ km}}{\frac{1}{3600}\text{ h}}$.
$105\times\frac{\frac{1}{1000}}{\frac{1}{3600}}=105\times\frac{3600}{1000}=105\times3.6 = 378\frac{km}{h}$

Answer:

378
