Answer:
distance = speed ×time
d=s×t
s1=16kmph,s2=24kmph
t1=2hours,t2=3hours
d=d1+d2
d1=s1×t1
=16×2
=32
d2=s2×t2
=24×3
=72
d=32+72
d=104km

Answer:
Total distance = 104 km
Average speed = 20.8 km/hr
Step-by-step explanation:
Given :
- Object moves with a speed of 16 km/hr for two hours
- Object moves with a speed of 24 km/h for next three hours
To find :
- Average speed
- Total distance travelled by the car
Distance = speed×time
Distance travelled in the first interval = 16×2
Distance travelled in the first interval = 32 km
Distance travelled in the second interval = 24×3
Distance travelled in the second interval = 72 km
Total distance distance = 72+32 = 104 km
The total distance covered by the car is equal to 104 km
Average speed = total distance / total time
Total time = 2+3 = 5 hours
Average speed = 104/5
Average speed = 20.8 km/hr
The average speed of the car is equal to 20.8 km/hr
