The speed of the airplane is 860 km / h, and the speed of the pedestrian is 215 times less. What distance will the airplane fly in the time it takes a pedestrian to cover 8 km?
Decision:
860: 215 = 4 km / h – pedestrian speed;
8: 4 = 2 hours – the time it takes a pedestrian to cover 8 km;
860 * 2 = 1720 km – the plane will fly in 2 hours (in the time that a pedestrian will cover 8 km).
Answer: 1720 km.
To solve the problem, you first need to find the pedestrian’s speed, since without it it will be impossible to calculate the time required for the condition. Then you need to find the time for which the pedestrian will cover the given distance. And finally, find the distance that the plane will fly in that time.
