Answer:

Usain Bolt runs 100 meters in 9.63 seconds.

There are 3600 seconds in 1 hour.

Therefore, his speed = (100 ÷ 9.63) × 3600

                                   = 37383.17757... meters per hour

                                   = 37383.2 meters per hour (1 dp)

25 miles per hour = 40233.6 meters per hour

Therefore, as 37383.2 < 40233.6 his speed is less than the speed limit.

Answer:

Usain Bolts' speed:

Usain Bolt (can run):
100 meters = 9.63 seconds.

3600 sc. = 1 h.

Thus, his speed is;
(100 ÷ 9.63) × 3600 =
10.3842159917 x 3600 = 37383.2 mph


Speed Limit:

The speed limit is about 403 meters per hour (40,233.6) or 25 mph

25 mph = 40,233.6 meters per hour (about 40,234 meters/hr)

We then compare the speed limit to Usain Bolts' speed.
Excact amounts:
37383.2 < 40233.6


About (rounded):
37,000 < 40,234


In conclusion, Usain Bolts' speed was less than the speed limit.
