How far can a subway car travel in 1 hour if its average speed is 0.96 miles per minute? - A particle 2

If the motion of a particle is described by the relation a(t) = 7t³ + 2 m/s², and the initial velocity of the motion is zero when t = 0 and the distance is 2m, t = 0.5s. Determine the velocity and displacement when t = 10s. - A speedboat

A speedboat goes 900 km against a current of 25 km/hr. Its trip took 10 minutes longer than it would have taken to travel with the current. What is the speedboat's speed in still water? - A boy 2

A Ferris wheel with a diameter of 100 feet makes five revolutions every 8 minutes. The base of the wheel is 4 feet above the ground. Your friend gets on at 3 PM sharp. a) Write an equation to express the height in feet of your friend at any given time in - Buses A and B

Bus A leaves Worcester at 08:00 and travels north along the N1 at 50 km/h. Bus B leaves Worcester at 10:00 along the same route at 70 km/h. At what time will bus B pass bus A? - Designated 71874

The patrol had started at a designated marching angle (an azimuth) of 13°. After 9 km, the azimuth's angle changed to 62°. The patrol went 10 km in this direction. Find the distance from where the patrol started. - A cyclist

A cyclist rides for 30 minutes on a style road to the top of a mountain. Down there, the road goes downhill. Its uphill speed is 20km/h and 60km/h downhill. The distance from the summit of the mountain to its destination is 30 km. Calculate the average sp - Lightning 69734

The sound travels at a speed of 1km in 3 seconds. If the thunder is heard 12 seconds after the lightning, what distance is the storm? - Increases 69454

The stork moves to Africa for the winter for an average of 10 hours a day and flies around 650 km. At what average speed does the stork move? - Cyclist 66904

The athlete ran on a 10 km route at a speed of 5 m/s, 10 minutes after him. A cyclist drove at a speed of 30 km/h. Who will be at the finish first (A or B)? - Vertically 65984

We threw the stone vertically upwards at a speed of v = 15m. s-1. How long will it be at a) 10 m, b) 12 m? - Brian 2

Brian and Jake left their homes 500 miles apart and drove straight toward each other. It took 4 hours for the two to meet if Jake's speed was 15 mph slower than Brian's. What was Brian's speed? - Kamal

Kamal walks to his school, which is at a distance of 3 km from his home, in 30 minutes. On reaching, he finds that the school is closed and comes back by bicycle with his friend and reaches home in 20 minutes. His average speed in km/h is - The tourist

The tourist will cross a 5 km long section in 3 hours. Part of the journey goes at a speed of 0.8 m/s and the other part at a speed of 0.4 m/s. Find the length of the first and second parts of the journey. - Calculating 58401
