Step-by-step explanation:
Since we have given that
Lina has a scale model of a modern train
Model is created at a scale is given by
1:48
Height of the model train = 102 millimeters
We need to find the actual height of the train.
Since there is direct variation between model and actual height of the train.
According to question,
Hence, the actual height of train = 4.896 meters.
Answer:
The kilometers Jupiter travel in 5 seconds is <u>64 kilometers</u>.
Step-by-step explanation:
Given:
As Jupiter revolves around the sun, it travels at a speed of approximately 8 miles per second.
1 mile is equal to 1.6 kilometers.
Now, to convert this speed to kilometers per second, and at this speed to find kilometers will Jupiter travel in 5 seconds.
So, to convert speed of miles per second into kilometres per second:
<em>1 mile = 1.6 kilometres.</em>
Thus, 8 miles = 8 × 1.6 = 12.8 kilometres per second.
Now, at this speed we calculate the kilometres Jupiter travel in 5 seconds by multiplying:
<em>In 1 second Jupiter travel = 12.8 kilometres.</em>
So, in 5 seconds Jupiter travel
Therefore, the kilometers Jupiter travel in 5 seconds is 64 kilometers.
