Answer:
4 [miles].
Step-by-step explanation:
1) the condition 'the entire trip took 5 hours' can be written as (where t_us - time spent upstream, t_ds - time spent downstream)
2) but the distance [D] upstream is equal the distance downstream, then the condition above can be written:
3) finally,
D=5*4/5=4 [miles].
Answer:
The answer to your question is: It is not made of gold.
Step-by-step explanation:
Data
density = 19.32 g/cm³
side = 5 cm
height = 6 cm
mass = 942 g
Formula
V =
L² = 5 x 5 = 25 cm²
V =
V = 50 cm³
density = 942 g / 50 cm³
= 18.84 g/cm³
It is not made of gold because the density calculated is lower than the density reported in books.
