The speed of the river's current is 5 mph. If a boat travels 20 miles downstream in the same time that it takes to travel 10 miles upstream, find the speed of the boat in still water. If a person rows to his favorite fishing spot 10 miles downstream in the same amount of time that he rows 5 miles upstream and if the current is 5 mph, find how long it takes him to cover the 15 miles. Smith Engineering is in the process of reviewing the salaries of their surveyors. During this review, the company found that an experienced surveyor can survey a roadbed in 6 hours. An apprentice surveyor needs 8 hours to survey the same stretch of road. If the two work together, find how long it takes them to complete the job.
