Step-by-step explanation:
Horse A travels twice the distance horse B travels.
It is because the distance, the circumference of circle, is the function of the radius. The circumference is directly proportional with the radius.
Since r₁ = 2r₂, the distance is:
- C₁ = 2πr₁ = 4πr₂
- C₂ = 2πr₂
The time of travel is same so the difference is reflected in the speed.
The horse A has twice the speed of horse B.
