A man jogs for 20 minutes at a rate of 6kph, then walks for 30 minutes at a rate of 3 kph, then sits and rests for 15 minutes and finally walks for 45 minutes.
Find the rule of the function that expresses his distance travelled as a function of time (in hours).
:
20 min is 1/3 hr
30 min is 1/2 hr
15 min is 1/4 hr
45 min is 3/4 hr
:
Dist = speed * time
d+=+6%281%2F3%29+%2B+3%281%2F2%29+%2B+0%281%2F4%29+%2B+3%283%2F4%29
d = 2 + 1.5 + 0 + 2.25
d = 5.75 mi
