Question

A man travelled a distance of 90km and then found that 2/5 of his journey was still left. Find the total length of his journey?

Answer 1

Answer:150

Step-by-step explanation:

Let x be the total length

x-90 = 2/5x

x- 2/5x = 90

(5x-2x)/5 =90

3x/5 = 90

x = 450/3

x = 150

Or an alternative or easier way

(3/5)x = 90

x = 450/3

x = 150
