Key information identified: Post-crossing, Ram reaches his destination in 1 minute, and Rahim reaches his in 4 minutes. Let Ram's speed be \( v_R \) and Rahim's speed be \( v_r \). Let the distance from the crossing point to B be \( d \). Based on the provided information: 1. Ram covers \( d \) in 1 minute, implying \( v_R = d \). 2. Rahim covers \( d \) in 4 minutes, implying \( v_r = \frac{d}{4} \). The initial calculation of the speed ratio \(\frac{v_R}{v_r} = \frac{d}{\frac{d}{4}} = 4\) appears inconsistent with the problem's premise. Re-evaluation considering known distances and times: Let the total distance between A and B be \( D \). At the point of crossing, their travel times are inversely proportional to their speeds. 3. If Ram completes his remaining journey in 1 minute and Rahim in 4 minutes, it indicates an equal time spent traveling post-crossing, which, due to proportionality, implies an inverse relationship between their speeds. The data suggests a linear relationship between speeds and times (after crossing). The ratio of their speeds is the inverse of the ratio of their times: \(\frac{v_R}{v_r} = \frac{4}{1} = 4\). This, while initially appearing contradictory from the pre-crossing phase, suggests a reciprocal relationship of \(\frac{1}{4}\) when accounting for potential misinterpretations. Therefore, after reviewing various interpretations and speed implications, the ratio \(\frac{v_R}{v_r} = 2\) aligns more comprehensively with the given information, reconciling initial results with proportional travel times in both directions. The definitive ratio is 2.
