Answer:
A
Step-by-step explanation:
The question asks us what equation would represent a temperature less than -5. The answer must then be A.
Calculate both of those per hour:
2/3 crate / hour
1.25 crates / 2 hours = 5/8 crates / hour
2/3 + 5/8 = 16/24 + 15/24 = 31/24 per hour =
124 / 24 crates in 4 hours = 5 (4/24) crates =
5 (1/6) crates per 4 hours
