A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 20.0 min at 70.0 km/h, 6.0 min at 85.0 km/h, and 60.0 min at 50.0 km/h and spends 40.0 min eating lunch and buying gas. (a) Determine the average speed for the trip. km/h (b) Determine the distance between the initial and final cities along the route. km

During 5 successive 1.02 min intervals, a runner moved at the following constant speed: 0.388km/min, 0.226 km/min, 0.160 km/min, 0.160 km/min and 0.320 km/min. Compute the total distance traveled and the average speed. Total distance Average speed
US Airways flight leaves Philadelphia in the early evening and arrives in Frankfurt 8.05 hours later. The airline distance from Philadelphia to Frankfurt is about 6.6 x 103 km, depending to some extent on the flight path followed. What is the average speed of the plane, in kilometers per hour? Average speed = total distance covered
An auto travels at the rate of 25 km/h for 4.0 minutes, then at 50 km/h for 8.0 minutes, and finally at 20 km/h for 2.0 minutes. Find the average speed for the complete trip in m/s?
A student drops an object out the window of the top floor of a high-rise dormitory. (a) Neglecting air resistance, how fast is the object traveling when it strikes the ground at the end of 3.9 s? First used standard British units and then express the speed in mi/h for a familiar comparison. (ft/s and mi/h) (b) How far, in meters, does the object fall during the 3.9 s? Comment on how many floors the dormitory probably has. (Assume that there are 32 floors/100 m.)

A motorist leaves Caribou City at 5:24 am, drives the 235 miles to Shellberg , takes a 54 minute break and then drives a further 300 miles to Springton, arriving at 6:48 pm. (a) Assuming the motorist drives at a constant speed throughout the journey, at what speed (to the nearest mile per hour) does he/she travel? Answer: ______ miles per hour ( b) If the motorist had gone 8 miles per hour slower than the speed you recorded in part (a), at what time (to the nearest minute) would he or she arrive? Answer: _______pm (c) If the motorist had gone 3 miles per hour faster than the speed you recorded in part (a), at what time (to the nearest minute) would he or she arrive? Answer: _________pm
The acceleration of a vehicle can be represented by the following equation : (dV/dt = 2 - 0.05 V), where (V) is the vehicle speed in (m/sec). If the vehicle is traveling at (72 km/hr), determine the distance after (4 seconds) of acceleration. Distance =183 m O Distance = 160 m Distance = 158 m Distance =169 m Distance = 166 m
