Question

Q 21) In countries like USA and Canada, temperature is measured in Fahrenheit,
whereas in countries like India, it is measured in Celsius. Here is a linear equation
that converts Fahrenheit to Celsius:
(i) Draw the graph of the linear equation above using Celsius for x-axis and
Fahrenheit for y-axis.
(ii) If the temperature is 30°C, what is the temperature in Fahrenheit?
(iii) If the temperature is 95°F, what is the temperature in Celsius?
(iv) If the temperature is 0°C, what is the temperature in Fahrenheit and if the
temperature is 0°F, what is the temperature in Celsius?Q 21)

Answer 1

Answer:

Speed = Distance/Time, in this case the train is 300m but let's not consider the trains length for this equation because it is replaced by the bridge's distance. Therefore,

Distance = 200m.

Time = X and Speed =25 m/s

When changing the equation to Distance/Speed= Time

200/25= 8s

The time taken is 8 seconds.
