From 10:0 to 12:00, the rise in temperature 4°C and from 15:00 to 17:00, the fall in temperature is 6°C. What is the avarage rate of
If an aeroplane travels at a speed of 450 km/h, how many meters does it travel in 10 s? ANS:
avg rate of change is (total change in temp)/(change in time)
= (4-6)/(2+2) = -1/2 °C/hr
10s = 1/360 hr, so
450 km/hr * 1/360hr = 450/360 = 5/4 km
