A: One lesson lasts 1.5 hours, so 18 hours of them is 18 / 1.5 = 12 lessons. If one lesson costs $30, then 12 lessons cost 12 * 30 = $360. The answer is 360.
Question: Sam went for a run in the morning. In the afternoon, he went grocery shopping and walked twice the distance through the store as he had run that morning. That evening, he went on a bike ride with his family and biked for 12 miles. In all, he went 18 miles that day. How many miles was Sam’s morning run?
Answer: Let X be the distance Sam ran. His walk through the store was twice the distance of his run, so his walk was 2X. He biked for 12 miles and went 18 miles in all, so he walked and ran 18 - 12 = 6 miles. Thus, his walk and run together were X + 2X = 3X = 6 miles. Thus, he ran X = 6 / 3 = 2 miles. The answer is 2.
[Question]Samuel is driving to San Francisco’s Comic-Con in his car and he needs to travel 600 miles to the hotel where he made a reservation. At first, he drives at 50 miles/hour for 3 hours straight, then he speeds up to 80 miles/hour for 4 hours. How far is he from the hotel?
[Answer]At first at 50 miles / hour he travels 50 miles / hours * 3 hours = 150 miles. After that, he speeds up, traveling 80 miles / hours * 4 hours = 320 miles. He travels a total of 150 miles + 320 miles = 470 miles. He is 600–470 = 130miles from the hotel. The answer is 130.
