Answer:
33 °C
Step-by-step explanation:
Put 92 where F is in the equation, and solve for C.
92 = 1.8C +32 . . . . substitute for F
60 = 1.8C . . . . . . . . subtract 32
60/1.8 = C ≈ 33.33 ≈ 33 . . . . . divide by the coefficient of C, round the result
The temperature is about 33 °C.
-- If one train covers 40 km per hour and the other one covers 60 km per hour,
then they reduce the gap between them at the rate of 100 km per hour.
-- Since they begin 30 km apart, they meet and crush the crow in 30/100 = 0.3 hour.
-- The crow's speed is 80 km per hour. In 0.3 hour, he covers 0.3 x 80 = <em><u>24 km.</u></em>
<u>Note:</u> 40 km/hr and 60 km/hr are speeds, not velocities.
