Answer:
The cyclist's average speed is 13.43 
Explanation:
Speed is a quantity that expresses the relationship between the space traveled by an object and the time used for it. That is, speed is the magnitude that expresses the variation in position of an object and as a function of time, which would be the same as saying that it is the distance traveled by an object in the unit of time.
Average speed relates the change in position to the time taken to effect that change:

In this case:
- total distance traveled= 32 km + 15 km= 47 km
- total time= 3 hours that the cyclist travels + 30 minutes of rest = 3 hours + 0.5 hours (being 60 minutes equal to 1 hour, then 30 minutes equals 0.5 hours) = 3.5 hours
Replacing:

and solving, you get:
speed= 13.43 
<u><em>The cyclist's average speed is 13.43 </em></u>

Some starburst galaxies are much brighter in infrared radiation than they are in visible light because the dust surrounding the galaxies warms up and emits infrared light after absorbing visible light. Because of this, starburst galaxies produce up to 98% of their total energy in the infrared, making them some of the brightest infrared objects in the cosmos.
A sort of radiant energy that we experience as heat but that is invisible to human eyes is infrared radiation (IR), often known as infrared light. The sun and fire are two of the most prominent sources of IR radiation, however all objects in the cosmos release some of it.
