Question
Select the correct answerTwo cyclists A and B start cycling at 21 km/hr and 24 km/hr towards each other.The meet after 1 hour and 12 minutes. How far (in km) were they from each other when they started?Options48543642
Solution
To solve this problem, we need to find the total distance covered by both cyclists.
Step 1: Convert the time they met into hours. 1 hour and 12 minutes is 1.2 hours.
Step 2: Calculate the distance covered by each cyclist and then add them together.
The distance covered by cyclist A is speed * time = 21 km/hr * 1.2 hr = 25.2 km.
The distance covered by cyclist B is speed * time = 24 km/hr * 1.2 hr = 28.8 km.
Step 3: Add the distances covered by both cyclists to get the total distance.
25.2 km + 28.8 km = 54 km.
So, the correct answer is 54 km.
