There are 5280 ft in a mile. 55*5280=290400. So the car is travelling 290,400 ft/hour
CD is the perpendicular bisector of another line AB which can be proven below.
<h3>What is perpendicular bisector?</h3>
Perpendicular bisector is a line that divides another line into two equal halves in such a way that it creates an angel of 90°.
To proof that CD is the perpendicular bisector of another line AB the following is carried out;
- Draw a line segment AB with length of about 5 cm.
- With any radius greater than 2.5 cm, and compass fixed at A, draw 2 arcs, one above and one below AB.
- With the same radius, compass at B, cut the 2 arcs drawn in step 2.
- The line joining these two arcs is the perpendicular bisector of AB.

<span>a/b = 3/5 ----- a = (3b)/5
a + b = 136 --- (3b)/5 + b = 136
3b + 5b = 680
8b = 680
b = 85
a = (3b)/5 = (3 * 85)/5 = 51
a = 85 and b = 51</span>
Answer:
3 and 17/24 cups of flour
Step-by-step explanation:
You need to make the denominator the same so find what number the 8 and 3 can both be turned into to make the same number. They can both be made into a 24. 8x3=24 so you multiply the 3 by 3 making 9. Do the same to the 1/3, multiplying both by 8 making 8/24.
2 9/24 and 1 8/24 which can be made into 3 17/24
