Question

A motorist travelled 122 kilometres before his first stop. If he had 10% of his journey to complete at this point, how long was the total ride?

Answer 1

Let the length of total ride be x km.
Then, 10 % of x = 122
\[ \Rightarrow \frac{10}{100}x = 122\]
\[ \Rightarrow x = 1220\]
∴ The length of total ride is 1, 220 km.
