Answer 1

Answer:

Its a good question ill answer,

Step-by-step explanation:

Solution:

Speed of car for first 30 minutes = 30 km h^{-1}

Speed of car for next 1 hour = 40 km h^{-1}

(a) total distance travelled by the car

First case

Speed = distance / time

distance = speed x time

= 30 x 0.5 ---- (30 min = 0.5 hour)

= 15 km
