Answers
Answer:
Explanation:speed of the car for 1 hr = 20 kmph
Distance travelled = 20 kmph * 1hr = 20 km
Break = 1/2 hr
Speed of the car for the next 1 ½ hr = 100 kmph
Distance travelled = 100 * 3/2 = 150 km
Total distance travelled =
(20 + 150) km = 170 km
Total time taken = ( 1 + ½ + 1½) hr
= 3 hrs
Avg. Speed = total distance travelled / total time taken
= 170 km / 3 hrs
= 56 ⅔ km/hr
