Answer:

It will take him <u>0.5</u> (30 minutes) less hours if he bicycles at a speed that is 3km/h faster.

Step-by-step explanation:

18 km/h x 210 minutes = 3,780

3,780/21km = 180 minutes = 3 hours

If we multiply the speed by the time we can find the distance, using that we can find the time it takes to travel the same distance with more speed (21km/s this time).

<u>Therefore, it will take 30 minutes less if he travels 2 km/s faster or 0.5 less hours</u>

I hope this helps!

Answer:

$45.58

Step-by-step explanation:

Divide 12 by 2 to get the price of the shirt that's half off which is 6. Then add the total of the two shirts which is 6 + 12 to get 18, and also add the price of the pants which is $25. So 18 + 25 is 43. Then multiply 43 by the sales tax of 6%. Change the equation to 43 multiplied by 0.06 and u get 2.58. Add the total plus the tax and u get an answer of 45.58.
