Question

a man moves from A to B at the rate of 4 kilometre and our had he move at the rate of 3 whole 2 by 3 kilometre and hour he would have taken 3 hours more to move that distance find the distance between a and b(step by step)​

Answer 1

Answer:

let the distance between Aand B be D km

and time taken when he moves with speed 3kmper hour is T

so 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
