Final answer:
It would take approximately 0.0705882 minutes (or 4.235 seconds) for the airplane to travel 1.00 km at a speed of 850 km/hr.
Step-by-step explanation:
To determine how long it would take for an airplane to travel 1.00 km at a speed of 850 km/hr, we can use the formula
Time = Distance / Speed
Substituting the given values, we get
Time = 1.00 km / 850 km/hr = 0.00117647 hr
To convert this to minutes, multiply by 60:
0.00117647 hr * 60 min/hr = 0.0705882 min
Therefore, it would take approximately 0.0705882 minutes (or 4.235 seconds) for the airplane to travel 1.00 km at a speed of 850 km/hr.
