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
We will see that the number of students that play both sports is given by the inequality:
5 ≤ x ≤ 9
<h3>
How to find the number of students that play both sports?</h3>
We do know that in the class, there are 15 students.
Such that:
- 9 of them play basketball.
- 11 of them play soccer.
If you add these numbers, you get:
9 + 11 = 20
This gives more than the number of students that we have, to get the minimum <em>number of students</em> that play both sports we subtract the number of students:
20 - 15 = 5
5 students play both sports, but this is the minimum number.
There is also the case where out of the 11 students that play soccer, there are 9 that play basketball (so 9 students play both sports) and 4 students don't play any sport.
So the number of students that play both sports is given by the inequality:
5 ≤ x ≤ 9
