Question

An object travels 20 metre in 4 seconds and then another 20 metre in 2 seconds. What is the average speed of the object?

Answer 1

Answer:

6.66m/s

Explanation:

given

total distance = 20+20=40m

total time = 4+2=6

average speed = total distance / total time

average speed = 40/6

average speed = 6.66

Answer 2

Answer:

6.66 m/s

Explanation:

$avg \: speed = \frac{total \: distance}{total \: time} \\ v \: avg = \frac{20 + 20}{4 + 2} \\ v = 6.66 \: \frac{m}{s}$
