A cruise ship maintains a speed of 13 knots (nautical miles per hour) sailing from San Juan to Barbados, a distance of 500 nautical miles. To avoid a tropical storm, the captain heads out of San Juan at a direction of 12° off a direct heading to Barbados. The captain maintains the 13-knot speed for 13 hours after which time the path to Barbados becomes clear of storms. (a) Through what angle should the captain turn to head directly to...
13. A car travels 30 miles at an average speed of 60 miles per hour and then 30 miles at an average speed of 30 miles per hour. What is the average velocity over the entire distance? What is the average velocity over the entire time?
A jogger ran 7 miles, decreased her speed by 1 mile per hour, and then ran another a miles. I her total jogging time was 2 hours, find her speed for each part of her run mph. The speed for the first part of her run was (Type an integer or a decimal.)
You are driving your car at a constant speed of 60 miles per hour. What is the speed (in miles per hour) of a point at the very top of your tire? The radius of your tires is 1 ft. what is the speed (in miles per hour) of a point at the very bottom of your tire in contact with the road?
You are driving your car at a constant speed of 60 miles per hour. What is the speed (in miles per hour) of a point at the very top of your tire? The radius of your tires is 1 ft.
Material: Rational Functions Between the speed of 50 miles/hour and 70 miles/hour, your gas mileage is a linear function of the speed at which you drive. Your car gets 40 miles/gal at a speed of 50 miles/hr and 30 miles/gal at a speed of 70 miles/hr. During a one-hour time period, your speed increases from 50 miles/hour to 70 miles/hour at a constant rate. How many gallons of gas does your car burn during this period? First, determine the number...
A construction zone on a highway has a posted speed limit of 40 miles per hour. The speeds of vehicles passing through this construction zone are normally distributed with a mean of 46 miles per hour and a standard deviation of 4 miles per hour. A. The fastest 10% of the vehicles passing through this construction zone are going at what speed?
Two persons both walk at a speed of 4 miles per hour. In an airport, the two walkers pass each other in opposite directions on moving walkways that run at 6 miles per hour. What is the magnitude of the velocity of one walker relative to the other?
