Correct Answer - Option 1 : 990 km
Given:
The speed of bus P and Q are 30 km/hr and 33 km/hr respectively.
Formula used:
Time = Distance/Time
Calculation:
Let the distance be x km
According to the question:
Time taken by the slower bus – Time taken by the faster bus = 3 hr
⇒ (x/30) – (x/33) = 3
⇒ (33x – 30x)/30 × 33 = 3
⇒ [3x/30 × 33)] = 3
⇒ x = 30 × 33 = 990 km
∴ The distance between the starting point and destination is 990 km.
