Acar traveled 3⁄4 mile in one minute at constant speed. what was the speed of the car in miles per hour? ? miles per hour (hint: convert one minute to a fraction of an hour.)

the fractions are set up so minutes cancel out

multiply the numerators to get 45 miles

multiply the denominators to get 1 hour

45 miles per hour

hope this helped

Distance traveled by car in one minute = 3/4 mile

The relation between hour and minutes is given by:

one hour = sixty minutes

one minute = 1/60 hours

so we can replace one minute by 1/60 hours

Distance traveled by car in one minute =3/4 mile

Distance traveled by car in 1/60 hour =3/4 miles

distance traveled by car in 1 hour = (3/4) ÷(1/60)

In division we take reciprocal of the number after division sign and multiply it with first.

Reciprocal of 1/60 is 60

so multiplying 3/4 and 60

So distance traveled by car in one hour is 45 miles.

Speed of car is 45 miles per hour .

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

people grow faster than other people.
