Two math problems The first car and the second car are traveling from the two places at the same time. The second car runs 45 kilometers per hour, and the second car runs 42 kilometers per hour. The two cars meet at the midpoint of 12 kilometers. How many hours after the two cars leave at the same time? 2. A shopping mall participated in the financial insurance, the insurance amount was 40000 yuan, and the insurance rate was 0.75%. Due to the accident, the value of the lost goods reached 6.5 million yuan, and the insurance company compensated 5 million yuan. How many million yuan did the shopping mall actually lose? 2. Change "the insured amount is 40 million yuan" to "the insured amount is 40 million yuan"

Change "the insured amount is 40 million yuan" to "the insured amount is 40 million yuan"

45-42 = 3 (km)
12 * 2 / 3 = 8 (hours)
650-500 = 1.5 million yuan
4 * 0.75% = 0.03 (ten thousand yuan)
150 + 0.03 = 1.503 million yuan
