Question

after travelling 2/5 of his journey, Joy found that he still had to cover 15 km.What is the total distance?​

Answer 1

Answer:

let total distance = xkm

Joy travelled 2x/5 km

rest of his journey is (x-2x/5) km

=(5x-2x)/5 km

=3x/5 km

so,

3x/5=15

=> 3x=15×5

=> x=15×5/3=5×5=25

total distance is 25 km
