Question

A rocket taking off will take 2 days to reach the Moon. The Moon is
384 000 km from Earth.
a The top speed on an expressway is 100 km/h. How does this speed
compare to the speed you calculated in part a?

Answer 1

Answer:

speed of rocket =distance travelled /time taken to reach moon

= 384000/48 (2days=48hrs)

=8000 km/hr--------(1)

speed of expressway=100km/hr------given------(2)

from (1) and (2) above,

speed of rocket = 80 into speed of expressway

OR

speed of expressway= speed of rocket / 80
