• 1.

A car moves with a constant speed through 3 Km in 5 minutes. What is its speed?

• A.

10 m/s

• B.

0.6 m/s

• C.

1 m/s

• D.

600 m/s

A. 10 m/s
Explanation
The car moves with a constant speed of 10 m/s because it covers a distance of 3 km in 5 minutes. To find the speed, we can convert the distance to meters by multiplying it by 1000 (1 km = 1000 m). So, the car covers a distance of 3000 m in 5 minutes. To find the speed, we divide the distance by the time taken, which gives us 3000 m / 300 s = 10 m/s.

A car travels for 800 km in 20 hours. The details of the journey are shown below.DurationDistance Covered0 - 6 hours200 km6 - 8 hours0 km(at rest)8 - 16 hours400 km16 - 20 hours200 kmCalculate the average speed of the journey?

• A.

54.5 km/h

• B.

44.4 km/h

• C.

40 km/h

• D.

63.89 km/h

C. 40 km/h
Explanation
The average speed of the journey can be calculated by dividing the total distance traveled (800 km) by the total duration of the journey (20 hours). 800 km / 20 hours = 40 km/h.

Rate this question:

• 3.

An aeroplane moves with a constant speed of 150 m/s. Find the distance travelled in 2 minutes?

• A.

18 Km

• B.

1800 m

• C.

300 m

• D.

300 Km

A. 18 Km
Explanation
The distance travelled by the airplane can be calculated by multiplying its speed by the time taken. As the speed is given as 150 m/s and the time is given as 2 minutes, we need to convert the time to seconds before calculating the distance. Since there are 60 seconds in a minute, 2 minutes is equal to 2 * 60 = 120 seconds. Therefore, the distance travelled by the airplane is 150 m/s * 120 s = 18000 meters, which is equivalent to 18 kilometers.

Rate this question:

• 4.

Lia runs at a constant speed of 4 m/s. What distance will he cover in 1 hr

• A.

14.4 Km

• B.

4 m

• C.

144 m

• D.

4 Km

A. 14.4 Km
Explanation
Lia runs at a constant speed of 4 m/s. To find the distance he will cover in 1 hour, we need to convert the speed from meters per second to kilometers per hour. There are 3600 seconds in 1 hour, so we multiply the speed by 3600 to get the distance in meters per hour. Then, we divide the distance by 1000 to convert it to kilometers. Therefore, Lia will cover a distance of 14.4 km in 1 hour.

Rate this question:

• 5.

A car is at rest. What is its speed?

• A.

0 m/s

• B.

10 m/s

• C.

1 m/s

• D.

5 m/s

A. 0 m/s
Explanation
Since the car is at rest, it means that it is not moving. Therefore, its speed is 0 m/s.
