Answer:
ur missing a x in the equation
96 grams of zinc. If the ratio is 4:11 and the 11 correlates to 264 than 4x:11x could be rewritten as 4x:264. 264/11= 24 and 24*4=96
Yesterday's time: t = 2 hr 20 min
Today's time: 0.73(2 hr 20 min) = 0.73 (2.333 hr) = 1.703 hr
This can be expressed in hours and minutes:
60 min
1 hr + 0.703 hr = 1 hr + 0.703 hr * --------------
1 hr
= 1 hr + 42.18 min
Rounded off to the nearest minute, we get 1 hr 42 min (answer)
