vitfil [10]

The  IUPAC name for a binary covalent compound lack prefixes such as mono, di, tri tetra etc.

A binary compound is a compound that is composed of only two elements. Many binary compounds could be made up of a metal and a nonmetal or even two nonmetals as the case may be. Examples of binary compounds include; SO2, NaH, K2S etc.

the amount of mammoths do not matter, because each walk the same speed.

so you only need to look at this.

7 hours to go 11 kilometers
&
? hours to go 22 kilometers

fast answer is. it's twice the distance so it will take twice as long. 14 hours.

solve answer.

7×60min = 420min
420min ÷ 11 kilometers = 38.18181818min per 1 kilometer.

38.18181818 • 22 = 839.999999min round up 840.

840min ÷ 60min = 14 hours
