I have a science quiz on speed and velocity, you know, v=d/t?

Well I understand it, but only sort of, like I know it, but I can't think of it properly.

Can you give me any practice problems like finding time, distance or velocity? Like, 45 k/m h for 30 minutes?

* 2. What is your average speed in each of these cases?

a) you run 100. m at a speed of 5.0 m/s and then walk 100. m at 1.0 m/s.

b) you run for 100. s at a speed of 5.0 m/s and then walk for 100. s at a speed of 1.0 m/s?

* 3. A rabbit and a turtle are practicing for their big race. The rabbit covers a 30. m practice course in 5.0 seconds, the turtle covers the same distance in 120 seconds. If the actual race is run on a 96 m course, by how many seconds will the rabbit beat the turtle?

* 4. A tsunami caused by an earthquake occurring in Alaska in 1946 consisted of several huge waves which were found to travel at the average speed of 790 km/hr. The first of the waves reached Hawaii 4 hours 34 minutes after the earthquake occurred. From this data, calculate how far the origin of the tsunami was from Hawaii.

* 5. Two cyclist race with nearly uniform speed on a 500. m course. The blue bicycle crosses the finish line 2.0 s ahead of the red bicycle. If the red bicycle maintained an average speed of 10. m/s, what was the average speed of the blue bicycle?

2. First you would be able to desire to choose how long the holiday took and how long the return took. then you certainly could desire to experience them up with a ratio. and then locate out the traditional. 600km = six hundred,000 meters holiday = six hundred,000/4 hundred = 1500 seconds return holiday = six hundred,000/six hundred = one thousand seconds entire holiday time replaced into 2500 seconds. So we could chop up it into 5 aspects, 500 seconds each and each. First holiday replaced into 3/5 of the time. return holiday replaced into 2/5 of the time. So we can try this: (4 hundred + 4 hundred + 4 hundred + six hundred + six hundred)/5 2400/5 480 conventional speed is 480 m/s 3. i think of it is going to likely be a million m/s. yet i may well be incorrect. because of the fact the wheel turns one entire time each, that's in touch with the floor for a million meter each and each 2nd.
