Mathematics 1 Deneme Sınavı Sorusu #1357102

A car moves along a road in such a way that its position at time t is f(t) = t³ + t² + t (metre). What is the average velocity over the interval [1, 5] equal to?

38,5

39,5

Yanıt Açıklaması:

For the car given, t₁=1 and t₂=5. The values of f at these points are f(t₁) = f(1) = 1³+1²+1 = 3,
f(t₂) = f(5) = 5³ + 5² +5 = 155. So, the average velocity is equal to (155 - 1)/(5 - 1) = 154/4 = 38,5 metres/seconds. The answer is B.
