Answer 2

Answer:

$\purple {Aɳsաҽɾ}$

➤Let us assume that,

➤The car travelled for 2 hour

➢So for one hour,

⇒Distance Travelled = Velocity × Time

⇒80 × 1

⇒80 km

➣For second one hour,

⇨Distance Travelled = Velocity × Time

⇨40 × 1

⇨40 km

⇨Total Distance Travelled = 80 + 40

⇨120 km

$\sf ➯Average \: speed = \dfrac{Total \: Distance}{Total \: Time}$

$\sf ➯\cancel \dfrac{120}{2}$

➾60 km/h.
