Answer:
21 minutes
Step-by-step explanation:
To cut a 5-ft log into 5 equal peices, you need to make 4 cuts (each cut cuts one piece from a whole log, the last cut divides the remaining log into two pieces).
If it takes 
minutes to make one cut, then it takes
minutes to cut the log into 5 equal pieces.
Answer:
168.13
Step-by-step explanation:
2.32 x 46= 106.72
106.72+ 61.41= 168.13
Answer:
7 minutes 48 seconds.
Step-by-step explanation:
Average speed for the whole journey is
distance / time, so
105 = (2*80)/ (t + t2)
where t is the time when it is moving and t2 is the time it stays at town Q.
Time for journey P to Q
= distance / speed
= 80 /120
= 2/3 hours,
Time for journey Q to P
= 80/110
= 8/11 hours
So t = 2/3 + 8/11
= 46/33 hours.
- and substituting in the equation for the whole journey:
160 / (46/33 + t2) = 105
105*46/33 + 105*t2 = 160
105 t2 = 160 - (105*46)/33
= 160 - 146.364
= 13.636
t2 = 13.636/105 = 0.1299 hours.
= 7 minutes 48 seconds.
