Two cars A and B, started simultaneously from the same point in opposite directions, car A towards west and car B moves towards East If speed of car B is 45kmph and after 35 minutes they cover the distance 65.5 km , what is the speed of car A?(in Kmph)

The cars travel in opposite directions, so their distances add. In 35 minutes (which is 35/60 hours), they cover 65.5 km together. Their combined speed is therefore 65.5 divided by (35/60), which equals 112.29 kmph approximately. Since car B travels at 45 kmph, car A's speed must be 112.29 minus 45, which equals 67.29 kmph. Option B (67.28) matches this calculation with minor rounding difference.
