bret and cindy took different routes to travel from point a to point e. bret took the route along a, b, c, d, and e. cindy took the route along a, f, and e and reached the destination in 2 hours. their routes are shown.
if bret's average speed was twice cindy's average speed, what was bret's average speed?
3 miles per hour
6 miles per hour
8 miles per hour
9 miles per hour

So, Cindy would have had to walk 6 miles. Indicated by the numbers along her path. And since she went 6 miles in 2 hours, she had an average speed was 3. (6/3). And since Bret’s speed was double hers, (3•2) his average speed was 6mph.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.

Domain eukarya; kingdom plantae should be the answer.
