a maximum speed, and airplane travels 2460 miles against the wind in 6 hours. flying with the wind, the plane can travel the same distance in 5 hours

I'm assuming you want to find the wind speed.

the ground speed against the wind is 410.

2460 / 6 = 410

the ground speed against the wind is 492.

2460 / 5 = 592

the difference is 82 mph, but you need to divide by 2 because speed is being added in one direction and subtracted in the other.

82 / 2 = 41

your final answer is 41 mph.

for pluto answer is 451
