Answer:
500 km
Step-by-step explanation:
The relationship between distance, speed, and time is ...
distance = speed × time
The units of speed and time must be compatible. Since we're given the rate in distance per hour, our time units must also be hours.
40 min = (40 min)(1 hour)/(60 min) = (40/60) hour = 2/3 hour
Then the distance the plane travels is ...
distance = (750 km/h)(2/3 h) = 500 km
The aeroplane travels 500 km in 40 min.
