Answer:
Everything
Step-by-step explanation:
We can keep every things in the blank boxes.
Going upstream: 432 km / 6 hours = 72 km/h
Going downstream: 384 km / 4 hours = 96 km/h
Going upstream against the current means that the effective speed is:
r_boat - r_current = 72
Meanwhile, going downstream with the current means;
r_boat + r_current = 96
Adding both equations (to cancel out r_current) gives:
2r_boat = 72 + 96
r_boat = 84 km/h
Substituting back into one of the original equations: r_current = 12 km/h.
Answer:
30+6x=100
Step-by-step explanation:
100-30=70
6*11= 66
The total number of rides he can go on is 11. He will have a remaining balance of $4.00 which is not enough to pay for another ride.
Hope this helps have a wonderful day
