(1) Yes
(2) Yes
(3) Hmm how did you arrive with your answer, because I'm getting,
= 70 + 40 + 2(30 + .29)
= 110 + 2(30.29)
= 110 + 60.58
= 170.58
or perhaps there is typo or missing info? And I'm also curious with your use of 'm' units.
Please check my answer and let me know if it is right or not.
25+.32m(800)=281
28+.30(400)=148
70+40+2(30+.29)=830 +.29m
