a. Two cyclists racing on parallel roads maintain constant speeds of 30 mi/hr and 25 mi/hr. The faster cyclists crosses the finish line one hour before the slower cyclist. How long was the race (in miles)? b. Because Boat A travels 1.5 times faster than Boat B, Boat B was given a 1.5-hr head start in a race. How long did it take Boat A to catch Boat B? c. A plane flew into a headwind and made the outbound...

A car travels along a straight line at a constant speed of 56.0 mi/h for a distance d and then another distance d in the same direction at another constant speed. The average velocity for the entire trip is 27.0 mi/h. (a) What is the constant speed with which the car moved during the second distance d? mi/h (b) Suppose the second distance d were traveled in the opposite direction; you forgot something and had to return home at the...

Suppose that a cyclist began a 459 mi ride across a state at the western edge of the state, at the same time that a car traveling toward it leaves the eastern end of the state. If the bicycle and car met after 8.5 hr and the car traveled 34.4 mph faster than the bicycle, find the average rate of each.

To measure the speed of a car, we use miles per hour (miles/hour or mi/h or mph). To measure the rate of a reaction we use molar concentration per second (M/s). 1- Imagine that you took a road trip. Based on the information in the table, what was the average speed of your car? time mile marker 3pm 24 8pm 169 2- What is the average rate of formation of I2? H2+2IF→2HF+I2 Time (s) I2 concentration (M) 5 1.10 15...

Question 2: A car hits a tree at an estimated speed of 25 mi/hr on a 3% upgrade. If skid marks of 120 ft are observed on dry pavement (F=0.35) followed by 250 ft (F=0.25) on a grass-stabilized shoulder, estimate the initial speed of the vehicle just before the pavement skid began.
