A train leaves at 13.23 and arrives at its destination at 14.05. If the train travelled 31 km, what was it's average speed in km/h? Give your answer rounded to 1 dp.

0.738 km/h

Step-by-step explanation:

It took 42 minutes from takeoff to get to its destination, so when you divide 31/ 42 (42 representing the time and 31 km representing the distance), you get 0.738 km/h

2nd one in the first row is correct

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
