Question

After travelling 40 km,Ran found that he covered only 4/5 journey find the length of his journey

Answer 1

hey...!!!

let the lengty of his total journey be x
distance he covered = 40 km
so,
x - 40 = x - 4/5x
x - 40 = ( 5x - 4x)/5
x - 40 = x/5
x - x/5 = 40
(5x - x ) / 5 = 40
4x/5 = 40
x = 40 × 5/4
x = 50
so, his total journey = 50 km

hope it helps...!!!

Answer 2

Distance travelled by ran =40km
he covered distance =4/5
length of his journey =5÷4×40
=50km
therefore 50 km of length of his journey
