Answer:

20 hrs

Step-by-step explanation:

distance = rate (speed) * time....d = rt....but we are looking for time (t), so let me rearrange this formula.......t = d / r

t = d / r

d = 240 km

r = 12 km / hr

now we sub

t = 240 / 12

t = 20 hr <=======

240 km / 12 km = 20 hours
So that mean that you can travel 240 Km per hour , with a speed of 12 km per hour , it will take 20 hours to travel 240 Km at 12 km per hour
