Question

An object travels 16 m in 4 s and then another in 16 m 2 s . Find average speed.

Answer 1

average speed =total distance/total time

= 16m+16m/4s+2s

=32m/6s

=16/3m/s

Answer 2

total distance travelled by the objective is equal 16m + 16 m =32m
total time taken = US + 2S = 6 s
average speed = time distance travelled / total unit taken.
$\frac{32 \: m}{6 \: s} m \: = 5.33 \: {ms}^{ - 1} \:$
therefore average speed of the object is 5.33
${ms}^{ - 1}$
