EXPLANATION.
A man driving his moped at 24 km/hr
reaches his destination = 5 minutes.
if he had driven at 30 km/hr he would have
reached his destination = 4 min before time.
To find how far is his destination?
According to the question,
Let the distance be = x km
time taken to cover x km at 24 km/hr
=> x/24 hr.
time taken to cover x km at 30 km/hr
=> x/30 hr.
difference between two timing
=> 5 + 4 = 9 minutes.
=> 9/60 hr.
Therefore,
=> x = 18 km
Distance = 18 km

Answer:
18 km
Step-by-step explanation:
Assume that the distance covered by man is x km.
Time = Distance/Speed
So, time taken to complete x km at 30 km/hr is x/30 hr.
Similarly, time taken to complete x km at 24 km/hr is x/24 hr.
Total time = (5 + 4) = 9 min = 9/60 hr
As per given condition,
→ x/24 - x/30 = 9/60
→ (5x - 4x)/120 = 9/60
→ x/2 = 9
→ x = 18
Hence, the distance is 18 km.
