Find the cardinal number for the following sets. A = {106, 107, 108, 109,... 131}
B = {106, 108, 110, ..., 206}
=
n(A) = _
n(B) = _

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.

40 i don’t know lololol
