i need some math help for this boy that i'm babysitting right now...?
it would be helpful if you could give me step by step directions into solving the problems. 1.Christina drove for six hours at an average speed of 45 mph. She drove 53 mph during the first two hours of her trip. How fast did she drive during the last four hours?2. Jonathan drove to the beach which is one hundred eighteen kilometers away, at sixty kph. He drove home the next day at seventy two kph. How many hours in total did Jonathan drive?3. Destiny drove to Jordan's house at 51 mph. Jordan's house is thirty nine miles away. Destiny arived at jordan's house at 2:58pm. What time did she leave?
