Question

A village P is 12km from village Q. If it takes 3 hours 20 minutes to travel from Q to P and back to Q by a boat. If the boat travels at a speed of 6km/h from P to Q and (6+x)km/h back to P, find the value of x.

Answer 1

So it takes 1 hour and 50 minutes 1 way and it takes 2 hours to do the first way, so in order to go back the other way they went faster.

Hope this helps and wasn't too confusing :)

Also I'm not a math genius so if this is wrong I'm sorry

Answer 2

I forgot to say this in my last one, but you still need to figure out how much faster they were going

Answer 3

A village P is 12km from village Q. If it takes 3 hours 20 minutes to travel from Q to P and back to Q by a boat. If the boat travels at a speed of 6km/h from P to Q and (6+x)km/h back to P, find the value of x.

since time = distance/speed,
12/6 + 12/(6+x) = 10/3
12/(6+x) = 4/3
4(6+x) = 12*3
x = 3
