Please help; I have no idea how to solve this!! The temperature in degrees Celsius (C) can be converted to degrees Fahrenheit (F

) using the formula F(C)= 9/5C+k, where k is a constant. Find k, if to C=−40°C corresponds F=−40°F.

a man drives for awhile at 45 mph. Realizing he is late ,he increases his speed to 60 mph and completes his 405 mile trip in 8 h
Harlamova29_29 [7]
By definition, we have the following equation:
 d = v * t
 Where,
 d = Distance
 v = rate
 t = time

 The total distance traveled will be:
 45t + 60 (8 - t) = 405
 Solving for the time we have:
 t = 5 s
 Answer:
 
he drives at 45 mph for 5 s
