Distance = Speed × Time
Distance travelled = (50 × 0.5) km + (30 × 0.26) km + (70 × 0.76) km
= 86 km
Average speed = Total distance / Total time
= 86 km / (0.5 h + 0.26 h + 0.76 h)
= 56.57 kmph
Distance travelled = (50 × 0.5) km + (30 × 0.26) km + (70 × 0.76) km
= 86 km
Average speed = Total distance / Total time
= 86 km / (0.5 h + 0.26 h + 0.76 h)
= 56.57 kmph
