Answer 1

Answer:

132 km

Step-by-step explanation:

let the distance between A and B be D km

and

time taken when he moves with speed 3km per hour is T

then , D=4T

again in the second case

D=(T+3)×11/3

from these two equations we get

11T+33=12T

T=33 hr

now D=4×33

=132km

Answer 2

Step-by-step explanation:
