Question

Multiply 343 m by 5 and convert to km.

janu16 · Answer

The equation is VELOCITY = DISTANCE/TIME. Or V = d/t
To solve this equation for d, multiply both sides by t.
v*t = d.  Now plug in the values for v and t.
343 m/s * 5 s = d
1715 m = d. This answer is in meters. Since there are 1000 m in a kilometer, divide 1715 by 1000 to get km.
1715m * 1 km/1000m = 1.715 km
