Answer:
Fran's upstream speed (against the current):
2.9 km/hr - 0.1 km/hr = 2.8 km/hr
Fran's downstream speed (with the current):
2.9 km/hr + 0.1 km/hr = 3.0 km/hr
Using the distance formula for calculating time:
rate x time = distance
time = distance / rate
Fran's upstream time = 9 / 2.8 = 3.21 hrs
Fran's downstream time = 9 / 3.0 = 3.0 hrs
Well you would divide distance by time and you should make sure that you do the trucks equation seperate from the cars equation other wise you would only get one answer and it looks like you need 2 so figure out the time an distance for each car then divide distance by time and that is your answer.
6(x+1)=24
6x+6=24
6x=24-6
6x=18
6x/6=18/6
x=3
