b) if Karl didnt drive along the same roads as Salma, explain how this will effect ur answer to part (a)

#

u wanna find the distance salma drove

#

Distance = speed x time

#

So 80km x 3

#

so total distance is 240km

#

and then Karl took 5 hours

#

so you have the distance and time

#

so to find speed

#

distance / time

#

so 240/5?

proud lodge May 3, 2023, 8:07 PM

#

yes

#

48km/h for Karl

#

And if they didnt drive along the same roads, then the distance will be different

#

which means we could get a quicker or slower average speed
