Question

Mark the correct alternative in the following question:

If a person travels 150 km in 5 hours, then the time taken by him to travel 180 km is
​
(a) 3 hours (b) 4 hours (c) 8 hours (d) 6 hours

Answer 1

As, the time taken by the person to travel 150 km = 5 hours

⇒ The time taken by him to travel 1 km = $\frac{5}{150}=\frac{1}{30}$ hours

So, the time taken by him to travel 180 km = $\frac{1}{30}\times 180$ = 6 hours

Hence, the correct alternative is option (d).
