Answer:

315 kilometers.

Step-by-step explanation:

We know that:

30 kilometers = 1 hour

Solution:

30 kilometers = 1 hour
=> 30 x 21/2 kilometers = 21/2 hours
=> 15 x 21 kilometers = 21/2 hours
=> 315 kilometers = 21/2 hours

Hence, in 21/2 hours, the cyclist rides 315 kilometers.

Speed=30km/h
Time=21/2=10.5h

$\\ \tt\hookrightarrow Speed=Distance/Time$

$\\ \tt\hookrightarrow Distance=Speed\times Time$

$\\ \tt\hookrightarrow Distance=30(10.5)$

$\\ \tt\hookrightarrow Distance=315km$

Answer:

$\text{A. }y=1.30x+1.50$

Step-by-step explanation:

The two ringtones will cost her a total of $0.75\cdot 2=1.50$ and is a fixed amount. The relationship between the cost and number of songs only is $y=1.30x$ and therefore the answer is $\boxed{\text{A. }y=1.30x+1.50}$ . You can also directly find the answer by finding the y-intercept (in this case $1.50$ ), as no other answer choices include the term $1.50$ , so A must be the correct answer.
