1)How is displacement different from distance? Under what conditions can an object travel a certain distance and yet its resultant displacement be zero?
Displacement is a vector quantity while distance is a scalar quantity. If an object goes round-trip its displacement will be zero.
2)What is the distance traveled by a vehicle in 12 minutes, if its speed is 35 km/h?
= 74 km
Jon, think. If he was taveling at 35km/hr for an hour, he would have went 35km. He traveled for 1/5 of an hour.
The answer is obviously wrong. It has to be about 7km (1/5 of 35)
Then, to top it off, you divided time by speed. Hmmmm. distance=velocity*time
