Ответ:
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.
