There and back julian biked a 24 km trip to guelph. on his way there, his average speed was 12 km/h. on his way home, he stopped for a break, so his average speed was only 8 km/h. what was his average speed, in km/h, for the entire round-trip?

Time taken by Julian to complete 24 km trip to Guelph at 12 km/h =

hours

Time taken by Julian for return trip at 8 km/h = hours

As given, the total distance is 24 + 24 = 48 km.

And the total time is 2 + 3 = 5 hrs.

Hence, the average speed for the entire trip is =

The answer is 9.6 km/hour.

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.
