distance = rate * time
1st leg: d=r*7
2nd leg: d=(r+12)*5
7r=5r+60
2r=60
r=30 km/hr
d=30*7=210 km

What is the distance traveled in a certain amount of time called?
Velocity.
What is the origin of miles per hour?
A unit of distance (miles) traveled in a certain time period (one hour) to calculate speed. Speed=(time/distance).
What is definition of average speed?
The average rate of movement, for example the number of feet traveled in a certain number of seconds, or the number of miles traveled in a certain length of time.
What does a single point on a distance time graph show?
The distance from start at which a certain object is located at a certain time.
The set of points in a plain at a certain distance from a certain point?
That's a circle.
If you have a force acting on an object for a certain period of time how can you find the distance traveled?
There are two ways to find the distance traveled. One is to measure the distance traveled. The other is to measure the distance raveled within a certain amount of time and then multiply to find how far it will travel in the future.
What is the distance traveled in a certain amount of time called?
Velocity.
Why is velocity-displacement divided by time?
velocity means the distance traveled in certain time and in a certain direction. Therefore: velocity is the result of dividing the traveled distance by time taken, and adding a direction to it.
What does speed mean in a scientific way?
speed is the distance traveled in a certain time :)
If you know the distance of an object has traveled in a certain amount of time you can determine the?
speed
If you know the distance an objcet has traveled in a certain amount of time you can determaine?
Average speed.
If a person knows the distance an object has traveled in a certain amount of time they can determine the?
If you divide he distance by the time, and take into account the direction traveled, you will get the AVERAGE velocity during the time considered.
If a person knows the distance an object has traveled in a certain amount of time they can determine the .?
If you divide he distance by the time, and take into account the direction traveled, you will get the AVERAGE velocity during the time considered.
What can you determine if you know the distance an object has traveled in a certain amount of time?
Velocity Velocity= distance/time V=d/t
What is an object that has traveled a certain distance but has no velocity?
a car or any automotive going in circles, it has no direction 8)
What is the origin of miles per hour?
A unit of distance (miles) traveled in a certain time period (one hour) to calculate speed. Speed=(time/distance).
If you know the distance an object has traveled in a certain amount of time what can you determine?
You can determine the rate of motion. For example mph (miles per hour) is found by multiplying miles traveled by the time (hours) in motion.this formula isRate * Time = Distance
