Question

An object moves through 10m in 2min and the next 10m 8n 3min . Calculate it's average speed.​

Answer 1

Answer:

Explanation:

Time taken to travel 20 km with speed 60 km/hr = 20/60 = 1/3 hr = 20 min

 

Time taken to travel total distance = 2 + 20 = 22 min

 

Total distance = 20000+10 = 20010 m

 

average speed = Total distance / Total time = 20010 / (22×60) = 15.16 m/s

Answer 2

Answer:

1/15 m/s

Explanation:

= Distance [1] = 10 m

= Time [1] = 2 min = 2×60 = 120 s

= Distance [2] = 10 m

= Time [2] = 3 min = 3×60 = 180 s

= Average Speed:

= Total Distance / Total Time taken

= [10 + 10] / [120 + 180)]

= 20/300

= 1/15 m/s
