The first: rate*time*people = cost.
work = rate x time rate = work x time time = work x rate (also the x is a times symbol not a variable:) )
interest = prinsciabl x rate x time
distance= rate X time
V=D/T This means volisity = distance/time
Distance= Rate x Time
Distance = Rate x Time Rate = Distance/Time, not Time/Distance
I=prt means i=principle x rate x time
Multiply the quantities you know. Distance = (rate) x (time)
Interest = Principal x Rate x Time therefore, Time = Interest/ (Principal x Rate) Time = 600/(2500 x 0.06) Time = 600/150 Time = 4 years
Principle X Rate/time
Distance = Rate x Time
