The speed of a train increases from 650 km/hr to 800 km/hr in 5 hours. What is its acceleration?

\overline{a} = \frac{v - v_0}{t} = \frac{\Delta v}{\Delta t}

Step-by-step explanation

i do not really understand but use this formula

=average acceleration

v=final velocity

v_0=starting velocity

t=elapsed time

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.
