Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2 h, and Car B traveled the dista
Yuki888 [10]
d=v \cdot t
d - distance
v - speed
t - time

Car A:
v_1 \\
t_1=2 \\
d_1=v \cdot 2=2 v

Car B:
15 mph faster than car A
v_2=v_1+15 \\ t_2=1.5 \\ d_2= (v_1+15) \cdot 1.5=1.5v_1 + 22.5

Both cars traveled equal distances:
d_1=d_2 \\
2v_1 = 1.5v_1+22.5 \\
2v_1-1.5v_1=22.5 \\
0.5v_1=22.5 \\
v_1=45 \\ v_2=45 + 15 =60

Car B traveled at the speed of 60 mph.

An amusement park sold 810 discount tickets and 90 full-price tickets. What percentage of the tickets sold were discount tickets
blondinia [14]

Answer:

90%

Step-by-step explanation:

First, find the total number of tickets sold.

810 discount + 90 full-price = 900 tickets

Now you need to find what percent 810 is of 900.

% of 900 = 810

810/900 = 0.9

Convert this to a percentage.

0.9 × 100% = 90%

90% of tickets were sold at a discount.
