Express 63 km/hr into meters/sec.

Answer

To convert 63 km/hr into meters/sec, we can follow these steps:

### Step 1: Understand the conversion factor
We know that:
1 km/hr = 10/36 m/sec

### Step 2: Set up the equation
To convert 63 km/hr into m/sec, we multiply by the conversion factor:
63 km/hr = 63 * (10/36) m/sec

### Step 3: Perform the multiplication
Now, calculate:
63 * (10/36) = 630/36 m/sec

### Step 4: Simplify the fraction
Now, we need to divide 630 by 36:
630 ÷ 36 = 17.5 m/sec

### Step 5: State the final answer
Thus, 63 km/hr is equal to 17.5 m/sec.
