Abicyclist was going from point a to point b with a speed of 12 km/h. on the way back he increased his speed to 18 km/h and covered the distance in 15 minutes less. what is the distance between point a and point b?

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
