Answer:
speed of car A =Speed of car B=0.8 miles/minutes.
Step-by-step explanation:
We are given that speed of car A is equal to speed of car B.
Also let car A travels x miles.
and car B travels y miles.
Car A reaches its destination in 17 minutes.
this means that speed of car A is given by: 
miles/minutes ( since speed is defined as the ratio of distance and time).
Car B reaches its destination in 32 minutes.
This means that the speed of car B is given by: 
miles/minutes
as speed of both cars are equal this means:
------(1)
Also we are given Car B travels 12 miles farther than Car A.
this means 
------(2)
on using equation (1) and (2) we have:
Hence the speed of car A is 0.8 miles/minutes ( since x/17 is the speed of car A)
Speed of car B=0.8 miles/minutes.
Answer: 1/4
Explanation: Because there is a 1/2 chance that a female will get the first job, and a half chance that a lady will get a second job. So (1/2)*(1/2)=(1/4)
Answer:
It's when rates are expressed as quantities.
Step-by-step explanation:
An example would be miles per hour (mph). People use these to determine the distance they will go in an amount of time and to judge safe speed.
Step-by-step explanation:
Below is an attachment containing the solution
By trial and error, I got it first correctly. The granola
bars cost $1 each and the yogurt is $.50 per cup. By plugging this in to each
equation, you'll see that 12 granola bars equals $12, and 7 cups of yogurt
equals $3.50, for a total of $15.50. The second account would produce $6 +
$5.50, which equals $11.50.
