Answer: 22.55 mph
Step-by-step explanation:
Let the speed of the train be n
4 × 62 = 248 which is the distance travelled by the car in 4 hours and the train travelled in 11 hours
11 × n = 248
11n = 248
n = 248/11
n = 22.55mph
Let x = the other rational number.
x(66/7) = (48/5)
Solve for x to find your answer.
Practice is key in mathematics! Always search up the topic and re-read the lessons with some practice problems to see if you got it. Asking your teacher and peers to help is another way to go.
Remember, your teacher had to learn this in order to teach you about it!
