Answer:
Step-by-step explanation:
You are looking for car b speed.
Car A traveled the distance in 2 h, and Car B traveled the distance in 1.5 h. Car B traveled 15 mph faster than Car A.
Formula r×t=d
2(s-15) = 1.5s
2s - 30 = 1.5s
2s - 1.5s = 30
0.5s = 30
S= 30/0.5
s peed of car b = 60 mph

Step-by-step explanation:
Answer:
The stone would take approximately 10.107 seconds to fall 500 meters.
Step-by-step explanation:
According to the statement of the problem, the following relationship of direct proportionality is built:
Where:
- Time spent by the stone, measured in seconds.
- Height change experimented by the stone, measured in meters.
- Proportionality constant, measured in .
First, the proportionality constant is determined by clearing the respective variable and replacing all known variables:
If and , then:
Then, the expression is . Finally, if , then the time is:
The stone would take approximately 10.107 seconds to fall 500 meters.
