Answer:
59 F
Step-by-step explanation:
F=1.8C+32
Let C = 15
F = 1.8 (15) +32
Multiply 1.8 times 15
F = 27+32
F = 59
15 degrees C is 59 degrees F
that would be 3 minutes and 45 seconds (:
first of all you add all of the ratios together so it would be 1+3+5
That equals 9 then divide 72 by 9 which gets you 8. Then you times 8 by all of the ratios to get the answer
8:24:40
