A cheetah can run 112 km/h over a 100 m distance. What is the speed in millimeters per minute?

Question

This question is very hard for me and it's from my honors chemistry homework.

Answer 1

(112km/hora)*(100,000 mm/Km)*(1hora/60min.)= 186,666.66 mm/min.

Answer 2

    112km / h

=  [112km * (1000m / 1km) * (1000mm / 1m)] / [1h * (60min / 1h)]

=  (112 * 1000 * 1000 mm) / (60 min)

=  (112 * 1000 * 1000 / 60) (mm/min)

=  1,866,666.67 (mm/min)

=  1.867 * 10^6 (mm/min)
