How to calculate the speed of two planes?

What are the speeds of plane A and plane B?

Plane A flies 600 km in 3 hours, while plane B flies 500 km in 4 hours. How much faster is plane A than plane B?

Answer:

Plane A flies 75 km/hr faster than plane B.

To calculate the speed of two planes, we first need to find the unit rates for each plane.

For plane A: 600 km / 3 hr = 200 km/hr

For plane B: 500 km / 4 hr = 125 km/hr

Therefore, plane A flies 75 km/hr faster than plane B.
