Speed is how fast an object moves through time. Did you know that the average speed of a common snail is 0.001 m/s (meters per second), whereas the average orbital speed of planet Earth is 29,783 m/s?

Take your time and see how much you know about speed in our third Science quiz on the subject.

1 .
If distance is measured in meters and speed in m/s, time is measured in .......
seconds
minutes
hours
None of these
2 .
A car travels at 70mph. How long will it take to travel 210 miles?
20 minutes
2.1 hours
3 hours
7 hours
Time = 210miles/70mph = 3 hours
3 .
If distance is measured in miles and speed in mph, time is measured in .......
seconds
minutes
hours
None of these
4 .
How long would it take to travel 3km at a speed of 15m/s?
5 seconds
200 seconds
45 minutes
2 hours
3km = 3,000m so time = 3,000m / 15m/s = 200s
5 .
If distance is measured in kilometers and speed in km/h, time is measured in .......
seconds
minutes
hours
None of these
6 .
How long would it take to travel 300,000m at a speed of 60km/h?
0.5 hours
5 hours
5,000 minutes
5,000 hours
300,000m = 300km so time = 300km / 60km/h = 5 hours
7 .
How long would it take to travel 100km at a speed of 50km/h?
2 hours
60 minutes
5,000 seconds
5 hours
Time = distance/speed so 100km / 50km/h = 2 hours
8 .
How long would it take to run 400m at a speed of 5m/s?
20 seconds
80 seconds
80 minutes
8 hours
Time = distance/speed so 400m / 5m/s = 80s
9 .
A cheetah can run at 100km/h. How long will it take to run 100 meters?
1 second
0.001 hours
1 minute
1 hour
100m = 0.1km so time = 0.1/100 = 0.001 hours, 1 hour = 3,600 seconds so 0.001h = 3.6 seconds!
10 .
How long would it take to run 800m at a speed of 8m/s?
80 seconds
100 seconds
1 hour
100 minutes
Time = distance/speed so 800m / 8m/s = 100s
