Speed, distance and time

From the question, we are to determine how long it would take the airplane to travel a distance of 640 kilometers.

From the give information,

The airplane flies with a constant speed of 640 km/h.

Speed = 640 km/h

Distance to be covered = 640 km

From the formula,

$Speed = \frac{Distance}{Time}$

We can write that

$Time= \frac{Distance}{Speed}$

∴ $Time = \frac{640 \ km}{640 \ km/h}$

Time = 1 hour

Hence, the time it would take to travel a distance of 640 kilometers is 1 hour
