Q
Q: A man can walk at a speed of 5 km/h. If he walks in a direction opposite to the wind blowing at 3 km/h, what is his effective speed?
Solution:
Effective speed = speed of man + speed of wind = 5 + 3 = 8 km/h.
Steps: 5
Show Steps
Step 1: Identify the speed of the man, which is 5 km/h.
Step 2: Identify the speed of the wind, which is 3 km/h.
Step 3: Since the man is walking in the opposite direction to the wind, we need to add the speed of the wind to the speed of the man.
Step 4: Calculate the effective speed by adding the man's speed and the wind's speed: 5 km/h + 3 km/h.
Step 5: The result of the addition is 8 km/h, which is the effective speed.
