$3.50 cause you divide $84 by 24
Average speed = Total distance/Time
A = 550km/6.5hr
A = 84.6 km per hr
<span>The answer is: 1, 2, 7, 14 .

FIrst, list all the factors of 42 (positive integers):
________________________________________________________
1, 42
2, 21,
3, 14,
6, 7
_________________________________________________
Then list all the factors of 28 (positive integers):
____________________________________________________
<span> 1, 28
2, 14,
4, 7
</span>_____________________________________________________
Now, list all numbers that occur for BOTH the factors of "28" AND the factors of "42"

8/10 is close to 1(8/10 = 0.8 and 5 and up you round up)
4/9 is close to 0 (4/9 = 0.44 and 4 and down you round down!)
2 is 37.
to find 1, subtract 37 from 90.
1 is 53.
3 is 143.
