Final answer:
An airplane with a constant speed of 880 km/h can travel 1980 kilometers in 2 1/4 hours when you multiply the speed by the given time of 2.25 hours.
Step-by-step explanation:
The student asked how far an airplane traveling at a constant speed of 880 km/h can travel in 2 1/4 hours. To solve this, multiply the airplane's speed by the time of travel.
Firstly, convert 2 1/4 hours into a decimal, which is 2.25 hours. Then, use this time to calculate the distance:
Distance = speed × time
= 880 km/h × 2.25 h
= 1980 km.
So, the airplane can travel 1980 kilometers in 2 1/4 hours.
