Help I'm confused on #10 and I need it fast it's due tomorrow and if you could explain to me how you would do the problem that would be great thanks

Well we know the minimum temp is -40 and the maximum temp is 53.3 So difference means subtract so subtract 53.3 and -40 and get
C)93.3
hawley lake was -40
lake havasu 53.3
the difference is the distance between them
53.3 is 53.3 from 0 and 40 is 40 from 0
difference is 53.3 + 40 = 93.3
