What is the speed in km/min of a skater who travels a distance of 210 m in a time of 30 seconds

Respuesta :

Answer: 0.42 km/min

Explanation:

total distance traveled(in meters) = 210m

total distance traveled(in km) = 210 ÷ 1000 = 0.21 km

total time taken(in seconds) = 30 s

total time taken(in minutes) = 30 ÷ 60 = 0.5 s

speed =(distance traveled)÷(time taken)[in km/min] = 0.21 ÷ 0.5 = 0.42km/min
