During the pyramid-building era the ancient
Egyptians used two units of length, the palm
and the ell. An ell was 7 palms and a palm
was about 3 inches.
If a hawk is tracked at a diving speed of 3
ells per second, what is its speed in inches per
second?
1. 126 in/s
2. None of these
3. 63 in/s
4. 0.7 in/s
5. 98.6in/s
6. 21 in/s
7. 5.25 in/s
8. 1/3 in/s
9. 7in/s
10. 42 in/s
The hawk was going 3 ells per second, that would be 21 palms per second since every ell is 7 palms its just multiplying 3 with 7. Now, since the hawk is going 3 ells per second, you multiply the 21 by 3 and get 63.
