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.

How long would it take to run 400m at a speed of 5m/s?

[ ]	20 seconds
[x]	80 seconds
[ ]	80 minutes
[ ]	8 hours

Time = distance/speed so 400m / 5m/s = 80s

How long would it take to run 800m at a speed of 8m/s?

[ ]	80 seconds
[x]	100 seconds
[ ]	1 hour
[ ]	100 minutes

Time = distance/speed so 800m / 8m/s = 100s

How long would it take to travel 100km at a speed of 50km/h?

[x]	2 hours
[ ]	60 minutes
[ ]	5,000 seconds
[ ]	5 hours

Time = distance/speed so 100km / 50km/h = 2 hours

How long would it take to travel 3km at a speed of 15m/s?

[ ]	5 seconds
[x]	200 seconds
[ ]	45 minutes
[ ]	2 hours

3km = 3,000m so time = 3,000m / 15m/s = 200s

How long would it take to travel 300,000m at a speed of 60km/h?

[ ]	0.5 hours
[x]	5 hours
[ ]	5,000 minutes
[ ]	5,000 hours

300,000m = 300km so time = 300km / 60km/h = 5 hours

A car travels at 70mph. How long will it take to travel 210 miles?

[ ]	20 minutes
[ ]	2.1 hours
[x]	3 hours
[ ]	7 hours

Time = 210miles/70mph = 3 hours

10.

A cheetah can run at 100km/h. How long will it take to run 100 meters?

[ ]	1 second
[x]	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!
