Janelle and her family are traveling around Europe by train. Their trip will begin in Madrid, Spain, and will end in Rome, Italy. The first part of their train journey, from Madrid, Spain, to Barcelona, Spain, took 3 hours. Use this information to solve the problems below. Part A If the train went 390 miles in 3 hours, what was the speed of the train in miles per hour?

The correct answer is 130 miles per hour

Explanation:

The speed refers to the rate of movement of a body, based on the distance and time of the movement. Additionally, the general formula to calculate the speed is to divide the distances by the time or s (speed) = d (distance) / t (time). Moreover, this factor is measured in units such as kilometers per hour or miles per hour.

In the case presented, we know the total distance was 390 miles and the total time was 3 hours. The formula and process are shown below.

Speed=

Speed =

Speed= 130 miles per hour

Therefore, the speed of the train in miles per hour is 130

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

it could be 1,3 and more others to create a cylinder.
