Reasoning and answer: Since time is obtained by dividing distance and speed, then Skye took 3 km / 150 km per hr. = 1 / 50 of an hour to finish the first 3 kilometers of the race. His speed on the next 2 kilometers was 150 + 50 = 200 kilometers per hour. Hence, it took him 2 km / 200 km per hr. = 1 / 100 of an hour to finish the next 2 kilometers. His speed on the remaining 1 kilometer is 150 x 2 = 300 kilometers per hour. Hence, it took him 1 / 300 of an hour to finish the 1 kilometer. So, the total time it took for Skye to complete the race was 1 / 50 + 1 / 100 + 1 / 300 = 1 / 30 of an hour. Therefore, his average speed for the entire race was 6 km / 1 / 30 hour = 180 kilometers per hour.
The answer: 180

Reasoning and answer: Two pairs of sunglasses costs 2 x $50 = $100. So, Mary spent $100 + $100 = $200. Thus, two decks of basketball cards costs $200 - $150 = $50. Therefore, one deck of basketball cards costs $50 / 2 = $25.
The answer: 25
