Beacause 35 is less than 39 the frezzing point of butter is closer to the frezzing point of water which is 0

if 35 is LESS than 39

so +35 - 39 is -4 F°

the answer to the freezing point of (hehe) butter is -4 F°

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
