Answer :

To determine the distance an airplane will cover in [tex]\(\frac{25}{6}\)[/tex] hours, given that it covers 1020 km in one hour, we can follow these steps:

1. Identify the Rate:
The airplane travels at a rate of 1020 kilometers per hour.

2. Identify the Time:
We need to find the distance covered in [tex]\(\frac{25}{6}\)[/tex] hours.

3. Calculate the Distance:
To find the distance covered, we multiply the rate by the time.

[tex]\[ \text{Distance} = \text{Rate} \times \text{Time} \][/tex]

4. Substitute the Known Values:
Substitute the rate (1020 km/hour) and the time ([tex]\(\frac{25}{6}\)[/tex] hours) into the formula.

[tex]\[ \text{Distance} = 1020 \, \text{km/hour} \times \frac{25}{6} \, \text{hours} \][/tex]

Simplifying this multiplication,

[tex]\[ \text{Distance} = 1020 \times \frac{25}{6} \][/tex]

5. Perform the Multiplication:
Carry out the multiplication to find the distance.

[tex]\[ \text{Distance} = 4250 \, \text{km} \][/tex]

Thus, the airplane will cover a distance of 4250 kilometers in [tex]\(\frac{25}{6}\)[/tex] hours.
