The speed of 45 km/h states that in every hour = 60 minutes = 3600 seconds the car travels 45 km.
So in 6 seconds it travels 6/3600 = 1/600 this distance, that is:
45 x 1/600
= 45/600
= 3/40
= 0.075km
= 75m.
Total distance = 75 km time = 3 hours average speed = 75km/3hrs = 25 km/hr
well we know that we have two speeds and a time. So, initial speed = 80 final speed = 60 change in time = 6 Now acceleration in this case will be measured in kilometers per hour per second (i.e. every x seconds, y kilometers per hour are gained in speed) So we simply apply the formula Acceleration = (final speed - initial speed)/ change in time = (80 - 60)/6 = 20/6 = 3.6666667 km/h/s
To find the speed in meters per second (m/s), you can use the formula: speed = distance / time. In this case, the distance is 5 meters and the time is 0.2 seconds. Thus, the speed is 5 meters / 0.2 seconds = 25 m/s.
Average speed is 65 mph.
136.7 mph
75 miles per hour. the average speed is how many miles (or kilometers, inches, centimeters etc.) u can travel in one hour, seconds, etc. For cars, it is usually miles per hour or km per hour.
Total distance = 75 km time = 3 hours average speed = 75km/3hrs = 25 km/hr
well we know that we have two speeds and a time. So, initial speed = 80 final speed = 60 change in time = 6 Now acceleration in this case will be measured in kilometers per hour per second (i.e. every x seconds, y kilometers per hour are gained in speed) So we simply apply the formula Acceleration = (final speed - initial speed)/ change in time = (80 - 60)/6 = 20/6 = 3.6666667 km/h/s
At least 2. At freeway speed, 3-5.
if you mean are Canadian car's speed measured in kilometers then yes because Canada uses the metric measurement system
Between 80mph and 120 mph, high performance cars were usually between a top speed of 100 to 140.
To find the average speed, add up all the speeds and then divide by the number of speeds given. (45 + 37 + 34 + 40) / 4 = 39 mph. Therefore, the average speed of the cars is 39 mph.
distance in miles divided by time in hours equals MPH. or more simply put velocity X time = distance. For shorter distances you can use meters divided by seconds = mps
Average speed is 65 mph.
3 ms-2
The cars avg speed would be 66 km/ 3 hr which is 22kmh
Extremely fast: 1 hour = 3600 seconds speed = distance/time = 1 mi / 45 s = 1/45 mi/s = 1/45 mi/s x 3600 s/hr = 3600/45 mi/hr = 80 mph!
