The distance between Station A and Station B is 4.8 miles. The distance between Station B and Station C is 16 miles. A train takes 4 minutes to travel from Station A to Station B and another 12 minutes to travel from Station B to Station C. Find the average speed of the train for the whole journey from Station A to Station C in miles per hour. Please explain

78 miles per hour

Step-by-step explanation:

Formula for speed is Distance divided by Time. (D/T)

The distance between Station A and Station C can be found be adding the distance from A to B and B to C. (20.8 Miles)

Same concept would go for the time.

Time to get from A to B added with B to C. (16 Minutes)

However, the time is in minutes and the question calls for hours. Divide 16 by 60, you get around 0.27.

20.8 divided by 0.27 would be around 77.9, or 78 miles per hour.

Hope this helps :)

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
