Question

If a rocket travels 68,732 milometers in 3 hours, what is it's speed?

a) 23,000 Km/hr
b) 23,000 hr/km
c) 22,910 hr/km
d) 22,911 km/hr

Answer 1

v = 0.0229 km/h

Explanation:

Given that,

Distance, d = 68,732 milometers = 0.0687 km

Time, t = 3 hours

We need to find the speed of the rocket. The speed of an object is given by :

`v=(d)/(t)\\\\v=(0.0687)/(3)`

v = 0.0229 km/h

So, the speed of the rocket is 0.0229 km/h.
