My aunt reached my maternal uncle’s house in five hours by driving the car at a speed of 40 km/hr. Let’s work out using the Rule of Three method how long it would have taken if she would have drives the car at a speed of 50 k.m/hr.
theorem1:-
The Rule of Three is a Mathematical Rule that allows you to solve problems based on proportions. By having three numbers: a, b, c,
(a)Direct proportions rule of 3:-
if a
b
c
then ![]()
(b)inverse proportions rule of 3:-
if a
b
c
then ![]()
formula:- (i)direct method----![]()
(ii)indirect or inverse proportions xy=k

method used is called indirect or inverse proportions method
speed of car 40km/hr in 5 hour time
![]()
![]()
now 50km/hr speed will take time
![]()
![]()
Therefore 4hr is time take at speed of 50 km/hr to reaches houses
