Question

expresar una velocidad de 72km/h en m/seg; Km/min; y cm/seg

Answer 1

1 km = 1000m 1 h = 3600 s
72 km/h *  (1000 m / 1 km ) * ( 1 h / 3600s) = 20m/s


1 h = 60 min

72 km/h * ( 1 h / 60 min ) = 1.2 km/ min

1 km= 100000 cm
1 h = 3600s

72 km/h * (100000 cm / 1km ) * ( 1 h / 3600s) = 2000 cm/s
