Answer:
I think it is 10 km/hr
Step-by-step explanation:
5 hrs = 40 more with 2 km/hr current
2 hrs= less 40 no current
40-2x5=30
30 without current for three hours
30/3=10 km/hr no current
CHECK
10x2=20
10x5=50+2x5=60
Using the pythagoras theorem for a right-angled triangle:-
x^2 = 13*2 - 9^2 = 88
x = sqrt 88 = 2 sqrt 22
