Options

A. 810 km/h
B. 680 km/h
C. 750 km/h
D. 930 km/h

Answer

To calculate the speed of the jet, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Information**:
- Distance between the two airports: 2430 km
- Time taken by the jet to cover this distance: 3 hours

2. **Understand the Formula for Speed**:
- The formula for speed is given by:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

3. **Substitute the Values into the Formula**:
- Substitute the distance and time into the formula:
\[ \text{Speed} = \frac{2430 \text{ km}}{3 \text{ hours}} \]

4. **Perform the Calculation**:
- Divide 2430 km by 3 hours:
\[ \text{Speed} = 810 \text{ km/hour} \]

5. **State the Final Answer**:
- The speed of the jet is 810 km/hour.

### Summary:
The speed of the jet is 810 km/hour.
