Hunk travelled 540 km at an average speed of 90 km/h. If Tim

completed the same amount of distance with 1 hour and 30 min less

than Hunk, what was Tim's average speed for the whole journey?

km/h

120 km/h

Step-by-step explanation:

Hi, to answer this question, first, we have to calculate Hunk's time spent on his travel.

Speed rate = distance /time

Time = distance /speed = 540/ 90 =6 hours

Now, since Tim completed the same amount of distance with 1 hour and 30 min less (1.5) we have to subtract 1.5 hours to Hunk's time to calculate Tim’s time:

6-1.5 = 4.5 hours

Tim's speed rate = distance /time

s = 540/4.5 = 120 km/h

Feel free to ask for more if needed or if you did not understand something.  

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1
