Answer:
The speed of the jet is 410 mph.
Step-by-step explanation:
The jet and the passenger plane flew in opposite directions.
Given that the passenger plane flew at a speed of 450 mph, then after 11 hours, the passenger plane will fly (450 × 11) = 4950 miles.
Again, given that after 11 hours the passenger plane and the jet are 9460 miles apart.
Therefore, in 11 hours the jet flew (9460 - 4950) = 4510 miles.
Hence, the speed of the jet is mph. (Answer)
