The average speed can be obtained by the formula:
If a boat travels 36 miles in 1.5 hours ans then in 14 miles in 0.75 hour, then find:
- total distance is 36+14=50 miles;
- total time: 1.5+0.75=2.25 hours.
Therefore,
miles per hour.
Answer: 
miles per hour.
<span>integers are numbers that we get from adding and subtracting the number 1. Zero also belongs to integers .
</span><span>example
3 = 1+ 1 + 1
3 = 1 + 1 + 1 +1 - 1
0 = 1 + 1 - 1 - 1
- 4 = -1 - 1 - 1 -1
- 4 = 1 - 1 -1 - 1 - 1
</span><span>In this way you can get infinitely large number of total positive , negative and zero</span>
Answer:C
Step-by-step explanation:
180-(60+40)=80°
C=80°
20/sin80. =a/sin40
a=(20sin40)÷sin80
=13.1
