V = one-third B h B = 12 (12) = 144 feet squared What is the final step in determining the volume of the pyramid? V = one-third (144) (15) V = one-third (144) (12) V = one-third (144) V = one-third (12) (15)

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.

it should be a.

hope it
