Answer:
The driver took shorter than estimated
It took shorter by 2 hours( 120
minutes)
Step-by-step explanation:
Firstly we want to know if the drive took longer or shorter
By 2 days, the number of hours will be 2 * 24 = 48 hours ( recall 24 hours = 1 day
now , since 60 minutes give one hour, then 48 hours will me 60 * 48 = 2,880 hours
This is less than 3,000 hours
By how much?
Simply subtract the value of minutes in 48 hours from 3,000 = 3000-2880 = 120 minutes ( or two hours)
Kilogram, Mole, Candela, Ampere, Meter, Second and Kelvin are the 6 basic measures, so I guess Kilogram

Answer:
A: 244 pounds
B: 122 pounds
C: 274 pounds
Step-by-step explanation:
We have A+B+C = 640; A=2B; C=A+30. Substituting the last into the first gives ...
A + B + (A +30) = 640
2A +B = 610 . . . . . . . . . . . . subtract 30
Substituting the second into this equation gives ...
2(2B) +B = 610
B = 610/5 = 122 . . . . . divide by 5
A = 2B = 244 . . . . . . . .find A from B
C = A+30 = 274 . . . . . find C from A
Box A weighs 244 pounds; box B weighs 122 pounds; box C weighs 274 pounds.
Answer: 115 - (-30) = 115 + 30 = 145 degrees change
