A bus route has 20 stops at intervals of five minutes. Call the place where the route begins "Stop 0', and call the first stop after this "Stop
1", and so on. The relief bus driver, who is initially stationed at Stop O,
must meet the bus after it has been on route for seven and one
quarter hours. Answer the following questions to determine at which
stop the relief driver should meet the bus.
a. How many five-minute intervals make up seven and one
quarter hours?
(Hint: An hour has 12 five-minute intervals.)

b. How many stops will the bus have made after seven and one
quarter hours?

C Fill in the blanks: After seven and one quarter hours, the
number of the stop where the bus will be is the remainder
that is obtained when ———- is divided by ————-
d. At which stop should the relief bus driver meet the bus?

Submarines control how much they float or sink in the ocean by changing the volume of air and water contained in large ballast tanks. when the tanks are completely full of water, the submarine increases its overall mass and sinks down to the bottom. when the tanks are completely full of air, the submarine reduces its overall mass and floats to the surface. depending on the density of the seawater surrounding the submarine, it will pump seawater in or out of the tanks in order to achieve the same overall density as the sea water and float neutrally in the water. the volume of the submarine never changes. when the tanks are completely full of water, a submarine with a volume of 7.8\times10^3\text{ m}^37.8×10 3 m 3 7, point, 8, times, 10, start superscript, 3, end superscript, space, m, start superscript, 3, end superscript has a total mass of 8\times10^6\text{ kg}8×10 6 kg8, times, 10, start superscript, 6, end superscript, space, k, g. the density of the seawater is 10^3\text{ kg/m}^310 3 kg/m 3 10, start superscript, 3, end superscript, space, k, g, slash, m, start superscript, 3, end superscript. to make that submarine float neutrally, and neither float nor sink in the ocean, what volume of water does that submarine need to subtract from its tanks?
