The value of distance between the station and the city in terms of miles which train and car travelled at interval of 2 hours is 129.6 miles.
<h3>What is the rate of speed?</h3>
The rate of speed is the rate at which the total distance is travelled in the time taken. Rate of speed can be given as,
r=d/t
Here, (d) is the distance travelled by the object and (t) is time taken but the object to cover that distance.
The train traveled 1/3 of the distance at 30 mph and the remaining distance at 40 mph. Let <em>t</em> is the time the train has taken to travel and x is the distance it travelled. Thus,
After two hour a car left the same station traveled the first 3 hours at 35 mph and the remaining distance at 51 mph. Let <em>t</em> is the time the car has taken to travel and x is the distance it travelled. Thus,
As t is same, thus put the value of t in this equation,
Thus, the value of distance between the station and the city in terms of miles which train and car travelled at interval of 2 hours is 129.6 miles.

Step-by-step explanation:
3 more than twice n = 3+2n
3 more than twice n is atmost 50,
=> 3+2n <= 50 {(3+2n) is less than or equal to 50}
Answer:
This is Isosceles Right
Step-by-step explanation:
An Isosceles is a triangle that has two sides the same length and one side longer or shorter
An Right is an triangle with a 90˚
