- At noon, Fred is driving south on Highway 1, 50 miles north of its intersection with Highway 2. He is traveling at 40 miles per hour. At noon, Jill is driving west on Highway 2 through its intersection with Highway 1. She is traveling at 30 miles per hour. (a) When will Fred reach the intersection with Highway 2? (b) How far apart will the two cars be at that time? (c) When will the two cars be closest to each other, “as the crow flies”? (d) How far apart will they be at that time?you walk 1dkm north in 15 hours and then 18 km west for 2 hours what is the magnitude of your average velocityTwo buses start at the same time towards each other from terminals A and B, 8 km apart. The time needed for the first bus to travel from A to B is 8 minutes and of the second bus B to A is 10 minutes. How much time is needed by each bus to meet each other if they traveled at their respective uniform speeds. In what distance from A, in meters, the bus will meet?
- A high-tech drone flies over Miami, FL in a direction 50.4 west of north with a speed of 35.4 km/h. Three hours later, the drone suddenly shifts due north, and its speed slows to 19.2 km/h. How far (in kilometers) from Miami, FL is the drone 4.50 h after it passes over the Miami. Round your answer to 0 decimal places.The F-35A, one of the U.S. Air Force's latest fifth-generation fighter was taken 160 km away from the terminal with a speed of 30. km/h and released. The F-35A returned back to the terminal after 4 days. If we place the origin at the terminal and extend the +x-axis to the release point. With that, what is the distance traveled by the F-35A for the entire trip, the F-35A’s average speed in m/s for the entire trip, the F-35A’s average velocity in m/s for the return flight, and the F-35A’s average velocity in m/s for the entire trip?A car travels 90 meters due north in 15 seconds. Then the car turns 32° west of north and travels 40 meters. What is the magnitude and direction of the car's resultant displacement? To answer this problem, what two methods will give us the accurate answer?

Assuming the two vehicles do not deviate off course, how far apart are they after 2.5 hours?Marc left Town A at 8 a.m. and drove to Town B at an average speed of 60 km/h. 1 1/2 hours later, Ben left Town A and drove to Town B, follwing the same route as Marc. After travelling for 240 km, Ben caught up with Marc. (a) What was Ben's average speed? (b) How far apart were they at 2 p.m.?To get to his office from home, Greg walks 5 blocks north and then 2 blocks east.
