Knowing that the units of the ancient Egyptians were palm and ell, where 1 ell was 7 palms and 1 palm was 3 inches, the speed of a hawk tracked as 3 ells/s is equal to 63 in/s. The given options are not the correct ones.
We have that:
1 ell = 7 palms
1 palm = 3 inches
v: is the speed of the hawk = 3 ells/s
To find the speed of the hawk in inches per second, we need to convert 3 ells/s to in/s, as follows:
[tex] v = 3 \: \frac{ells}{s}*\frac{7 \: palms}{1 \:ell}*\frac{3 in}{1 \: palm} = 63 \frac{in}{s} [/tex]
Therefore, the speed of the hawk is 63 inches per second. The given options are not the correct ones.
