Question

Average speed of the object B will be *​

Answer 1

Answer:

Explanation:

We know that avg speed = $\\\frac{total distance}{total time}$

Total distance covered= distance at end - distance at beginning

= 44-12 = 32 m

total time = time at end - time at start

= 11 : 00 - 9: 30 = 1:30 or 90 mins

Avg speed of b = 32/90 = 16/45 = 0.3555.. meter per min or 32/1.5 = 21.333.. meter per hour
