Question

If a car travels at 60km per hours for 2 hours and then at the speed of 80 km per hour for 4 hour. what is the average speed

Answer 1

First distance=speed ×time=60×2=120km
Second distance =s×t=80×4=320km
average speed=total distance /total time =120+320/2+4=440/6=73.33km/hr

Answer 2

Answer:

First distance= speed × time=60 × 2 = 120

second distance = speed × time = 80 × 4 = 320

Average speed = total distance/ total time = 120 + 320/2 + 4 = 440/6 = 73.33Kilometer/ hour
