A car travels 3 km of distance in 10 minutes to reach the destination. On the return journey, the car travels the same distance in 15 minutes. What is the average speed of car in entire journey?
Answers
Answer:
4m/s
Explanation: First it travels 3km in 10 min. (3000m in 600sec)
When the car returns it travels 3km in 15 min. (3000m in 900sec.)
Avg.Speed= Total distance traveled/ Total time taken
3000+3000/600+900= 6000/1500
So, the answer comes 4m/s
This is the answer :)
Given,
The distance travelled by the car in the first round : 3km
time taken to travel the said distance = 10 min
Distance traveled at the second round: 3km
time taken to travel the distance = 15min
The formula for speed,
distance = speed× time.
speed = distance/ time
average speed = total distance/ total time taken
avg speed= (3000+3000)/ (10+15)
= 6000/25
= 240m/min
Hence,
The answer for the above question is, the average speed of the car is 240 m/min.
