It is given that to cover a certain distance a man takes 2 hours if he walks at a speed of 3km/hr
We will first find out the distance
speed = distance/time
3 = distance/2
distance = 3 × 2
= 6 km
Now, we have to find the time taken if he walks at a speed of 4 km/hr
So, speed = distance/time
4 = 6/time
time = 6/4
= 1.5 hour
Hence, the man will take 1.5 hours if he walks at a speed of 4 km/hr

Answer:
1.5 hours
Step-by-step explanation:
Speed = distance / time
3 km/hr = distance /2 hr
Therefore distance = 3 * 2 = 6 km
The same distance is covered with a speed 4 kmph
Time taken to travel = distance / Speed
= 6 km/ 4kmph
= 1.5 hrs
