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 :)

what is

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
