A car is traveling at a steady speed. It travels 1(1/2) miles in 2(1/4) minutes. How far will it travel in 26 minutes? In 1 hour?

17miles

40miles

Step-by-step explanation:

Given parameters;

Distance traveled by  the car = 1miles  = miles

Time taken = 2minutes  = minutes

Unknown:

Distance covered in 26minutes and in 1hr = ?

Solution:

Speed is the rate of change of distance with time.

   Speed  =

A. Insert the parameters and find the speed;

   Speed  = = x = miles/minutes

Distance covered in 26minutes;

   Distance  = speed x time

   Distance  = x 26  = miles  = 17miles

B. Distance covered in 1hr or 60minutes;

  Distance = x 60 = 40miles

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
