For Vehicle A (Triangle Area): Formula for distance covered by A: $= 0.5 \times OL \times OP$

Where: OL is the time interval, OP is the velocity of vehicle A at time L. For Vehicle B (Rectangle Area): Formula for distance covered by B: $= OL \times CK$

Where: OL is the time interval, CK is the constant velocity of vehicle B. Distance Ratio Formula: Formula for distance ratio (A:B): $= (0.5 \times OL \times OP) / (OL \times CK)$ This gives the ratio of the distances, which simplifies to: $= 0.5 \times OP / CK$

Example Calculation: If we assume: OP=$3$ (velocity of vehicle A), CK=$4$ (velocity of vehicle B), OL=$10$ (time interval), The result will be $0.5 \times 3 / 4 = 0.375$, or the ratio of the distances is 3:4.
