Answer 1

4250 km

Explanation:

`\Large\bf{GiveN,} \\`

• 
  `{Distance\:covered\: in \:1\:hour\:=\:1020\:km}`

• 
  `{Distance\:covered\: in \:25/6\:hour\:= }`
  `{ 25/6\:×\:distance\:covered\: in \:1\:hour}`

⠀⠀⠀
`\textbf{Distance\:covered\: in \:1\:hour}`

⠀⠀⠀⠀⠀
`\implies`
`\bf(25)/(6)` × 1020

⠀⠀⠀⠀⠀
`\implies`
`\bf(25×1020)/(6×1)`

⠀⠀⠀⠀⠀
`\implies`
`\bf(25500)/(6)`

⠀⠀⠀⠀⠀⠀
`\small{\underline{\mathcal{\green{ =\:4250\:km}}}}`

`\therefore`
`{\:\:\:Distance\: covered\: in \:25/6\:hrs\:by\:plane}`
`{⠀⠀⠀⠀⠀= 4250\:km}`

Answer 2

Answer: If the air-plane travels 1020 km in one hour, then it will cover 4250 km in 25/6 hours.

The formula which relates distance, speed, and time is given by d = rt, where d is the distance traveled, r is the rate of travel or the speed, and t is the time traveled. To find out the distance an aircraft will travel in t = 25/6 hours, we must first find out the speed r of the aircraft in kilometers per hour (km/hr) as shown:

d = rt

1,020 km = r(1 hr)

(1,020 km)/(1 hr) = [r(1 hr.)]/(1 hr)

1,020 km/hr = r(1 hr./1 hr)

1,020 km/hr = r(1)

r = 1,020 km/hr

Now, calculating the distance the aircraft will travel in t = 25/6 hours, we have:

d = rt

= (1,020 km/hr)(25/6 hr)

= (1,020)(25/6) km

= (1,020/6)(25) km

= (170)(25) km

= 4,250 km
