If a snowboarder was snowboarding down a cliff for 200m going at a speed of 15km/h how long would it take to r

Question

i need to know.

Answer 1

Convert the 200m to Km (divide by 1000)= 0.2Km.

Divide by the speed:

0.2Km/ 15 Km/hr= (you do the math, I'm not doing your homework for you!)

The Km units cancel each other, leaving you with time in hours.

Answer 2

More of a science question than a snowboarding question, but I remember basic physics:

The weight of the snowboarder doesn't matter (except for changing the speed - but that is given)

200m = 0.200km, so:

0.200km / 15km/h = 0.01333hours

0.01333hours * 3600sec/hour = 48 seconds

Good Luck with you homework
