Atrain travels at a constant speed of 35 feet per second. how many minutes will it take the train to travel exactly 70 miles? (note: 1 mile = 5,280 feet.)

Since one mile equals 5280 feet, the train has to travel

feet.

Every second the train travels 35 feet, so it takes the train

seconds to cover that distance. Since there are 60 seconds in a minute, to convert seconds in minutes you have to divide by 60:

So, it takes 176 minutes to the train to cover that distance.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
