Question 859683: joan jogs 4km at a speed of 3km/hr. How long does she jog for?
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
D = r*t
4 = 3*t
4/3 = t
1.3333 = t (this is approximate)
t = 1.3333 (this is approximate)
So she jogged for roughly 1.3333 hours
Since 4/3 hrs = (4/3)*60 min = 240/3 min = 80 min, this means that she jogged for exactly 80 minutes.
