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.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

probably .5

i can on others if necessary.
