A girl walking at the speed of 2 km/hr covers a certain distance in 7 ...
⇒ If distance is constant, then the Speed is indirectly proportional to Time (Product of Speed and Time is constant
⇒ S1 × T1 = S2 × T2
⇒ 2 × 7.5 = S2 × 5
⇒ S2 = (2 × 7.5)/5 = 15/5 = 3 kmph
∴ Speed of the cycle = 3 kmph
⇒ S1 × T1 = S2 × T2
⇒ 2 × 7.5 = S2 × 5
⇒ S2 = (2 × 7.5)/5 = 15/5 = 3 kmph
∴ Speed of the cycle = 3 kmph

A girl walking at the speed of 2 km/hr covers a certain distance in 7 ...
Let's solve the problem step by step.
Given:
- The girl walks at a speed of 2 km/hr and covers a certain distance in 7 hours 30 minutes.
- The same distance is covered by a cycle in 5 hours.
We need to find the speed of the cycle.
Step 1: Convert the time into hours
- 7 hours 30 minutes is equal to 7.5 hours.
- 5 hours remains the same.
Step 2: Calculate the distance covered by the girl on foot
- Speed = Distance/Time
- Distance = Speed * Time
- Distance covered by the girl = 2 km/hr * 7.5 hours
- Distance covered by the girl = 15 km
Step 3: Calculate the speed of the cycle
- Speed = Distance/Time
- Speed of the cycle = 15 km / 5 hours
- Speed of the cycle = 3 km/hr
Therefore, the speed of the cycle is 3 km/hr, which corresponds to option C.
So, the correct answer is option C) 3.
Given:
- The girl walks at a speed of 2 km/hr and covers a certain distance in 7 hours 30 minutes.
- The same distance is covered by a cycle in 5 hours.
We need to find the speed of the cycle.
Step 1: Convert the time into hours
- 7 hours 30 minutes is equal to 7.5 hours.
- 5 hours remains the same.
Step 2: Calculate the distance covered by the girl on foot
- Speed = Distance/Time
- Distance = Speed * Time
- Distance covered by the girl = 2 km/hr * 7.5 hours
- Distance covered by the girl = 15 km
Step 3: Calculate the speed of the cycle
- Speed = Distance/Time
- Speed of the cycle = 15 km / 5 hours
- Speed of the cycle = 3 km/hr
Therefore, the speed of the cycle is 3 km/hr, which corresponds to option C.
So, the correct answer is option C) 3.
