Answer:
Step-by-step explanation:
let they travel the distance between them alone
d = common distance traveled by both motorcycle and car = 540 miles
= time taken by motorcycle to travel distance between them
= speed of the motorcycle = 48 mph
time taken by motorcycle to travel distance between them is given as
= d/
=540/48
= 11.25 h
= time taken by car to travel distance "d" =11.25 - 2.25 = 9 h
= speed of the motorcycle
speed of motorcycle is given as
= d/
= 540/9
= 60 mph
when the car and motorcycle move towards each other, the relative speed is given as
v =
+
v = 60 + 48
v = 108 mph
t = time taken to meet
Time taken to meet is given as
t = d/v
t = 540/108
t = 5 h
Answer:
140°
Step-by-step explanation:
1. full the circle is 360°;
2. YZ+XY=360-80; ⇔ YZ+XY=280;
3. if YZ=XY, then YZ=XY=280/2=140, ⇒ YOZ=140°
1. 3.75+4.50=8.25- 5.25= $3 profit
She made 8.25 off selling bracelets to others, which adds money to her "account", but also spent money on crafting supplies, which results in her subtracting from her "account."
