Answer:
Line A is fastest and Line D is slowest
Explanation:
Line A is the fastest moving object because the bar is steepest. Line A travelled the furthest in the least time, so Line A is moving fastest. Line D is the slowest object because the bar is least steep. Line D travelled the least distance in the most time, so Line D moves the slowest.

At what point of thermometric scale does Kelvin scale reading coincide with Fahrenheit scale
Answer:
At 574.59 Kelvin, the Fahrenheit temperature will be 574.59 °F.
Explanation:
We first need to find a relation between the Kelvin scale and the Fahranheit scale. We'll use the Celsius scale to relate them.
The Kelvin and Celsius scales are related by the formula:
K = °C + 273.15
Solving for °C:
°C = K - 273.15
Besides, the Kelvin and Celsius scales are related by:
°C = 5 ⁄ 9(°F - 32)
Now we find a temperature, say X, where both scales coincide. Equating both formulas:
X - 273.15=5 ⁄ 9(X - 32)
Multiply by 9:
9X - 2,458.35 = 5X - 160
Simplifying:
4X = 2,458.35 - 160=2,298.35
Solving:
X =2,298.35 / 4 = 574.59
At 574.59 Kelvin, the Fahrenheit temperature will be 574.59 °F.
if it takes 3.5 hours for the Hogwarts Express, moving at a speed of 120 mi/hr, to make it from Platform 9 and 3/4 to Hogwarts, how far apart are they?
a high speed train travels with an average speed of 250 km/h. the train travels for 2 hrs. how far does the train travel
Answer:
The answer is 500 kmExplanation:
The distance covered by an object given it's velocity and time taken can be found by using the formula
distance = average velocity × timeFrom the question
average speed = 250 km/h
time = 2 hrs
We have
distance = 250 × 2
We have the final answer as
500 kmHope this helps you
Answer:
The answer would be 454 miles.
Explanation:
You multiply the average speed by time travelled. Hope this helps!
