Speed is a scalar, velocity is a vector and so the direction of motion is important for velocity. Total distance travelled = 3km + 4 km = 7 km Total time taken = 3/5 hours + 4/3 hours = (9+20)/15 = 29/15 hours Average speed = 7 / (29/15) = 7*15/29 = 3.6207 km per hour. Final location = 3 km E + 4 km N = 5 km away from the starting point (by Pythagoras) in the direction 53.13 degrees = arctan(4/3). So average velocity = 5 / (29/15) = 5*15/29 = 2.5862 km per hour in the direction given above.
30 km/h x 3 h = 90 km
Speed = distance/time km/hr = 90km/3hr 90/3=30 30km/hr
we know that , speed=distance/time distance =69 * 3 =207 km
there is a distance of 298 km between Paris and Dunkirk. The driving time is nearly 3 hours.
By plane: max. 3 hours By car: Paris-Bucharest 2 290 km (theoretically 26 hours at 90 km/h, but practically 3 days)
210 km 3 hours
3 hrs & 34 minutes is the same as 3.56666666666 hours. Divide this into 90 km and your answer is 25.233645 km/h (average)

It is a distance of 44 km.
Average speed is the total distance traveled divided by the time taken.Average speed = total distance traveled/time taken = 90 km/3 h = 30kph
The driving distance is about 291 km - roughly 3 hours of driving time.
The total distance covered is 200 km (80 km + 40 km x 3). The total time taken is 4 hours (1 hour + 3 hours). So, the average speed is 50 km/h (200 km / 4 hours).
