Let x = speed of the first car

the second car is 12 km slower so the seconds car speed is x-12

 they each drove 2 hours so 1st car = 2x
2nd car = 2(x-12)
 
they drove 360 km
 so you have 2x + 2(x-12) = 360
 solve for x

2x+2(x-12) = 360

2x + 2x-24 = 360

4x-24 = 360

4x = 384
x = 384/4
x = 96

1st car drove at 96 km per hour

slower car drove at 96-12 = 84 km per hour

Answer:

\frac{-50}{54} - \frac{40}{100} +1.65 = 0.32

Step-by-step explanation:

First of all, let us lay out the problem clearly:

\frac{-50}{54} - \frac{40}{100} +1.65

This can be solved using a calculator, by first simplifying the individual fractions first, to decimals, then computing the addition and subtraction.

using your calculator, punch (-50 ÷ 54), your results should be:

-50 ÷ 54 = -0.93

Next, punch ( 40 ÷ 100), you should get 0.4

Now, join the individual results together to get:

- 0.93 - 0.40 + 1.65

Finally, still using the calculator, input the values as shown:

- 0.93 - 0.40 + 1.65 = 0.32
