13. Calculate Mounika's average speed if she covers 1200 m in 12 min.​

Answer 1

Answer:

• Average Speed of Monika is 1.66m/s.

Explanation:

Given:-

• Distance ,d = 1200m
• Time taken ,t = 12min

To Find:-

• Average Speed ,Av.Speed

Solution:-

Average Speed is calculated total distance covered divided by total time taken .

Time 12 min = 12×60 = 720 s

• Av.Speed = Total Distance/total time taken

Substitute the value we get

→ Av.Speed = 1200/720

→ Av.Speed = 1.66m/s

• Hence, the average Speed of Monika is 1.66m/s.

Answer 2

Distance = 1200 m

Time = 12 min or 720 sec

Avg. Speed = 1200/720 m/sec

= 1.666... m/sec

= 1.67 m/sec
