The time ((t)) it takes to travel a distance varies directly with the distance ((d)) but inversely with the speed ((s)). ( t = \fracds ).
: Pay close attention to phrasing like "square of z2z squared ) or "square root of zthe square root of z end-root The Constant : Never assume joint and combined variation worksheet kuta
Use the second set of numbers (and your new equation with $k$ included) to find the missing variable. The time ((t)) it takes to travel a
( y ) varies jointly with ( x ) and ( z ). If ( y = 30 ) when ( x = 2 ) and ( z = 5 ), find ( y ) when ( x = 3 ) and ( z = 4 ). ( y ) varies jointly with ( x ) and ( z )
