Answer 1

• Answer: FKFKK

FFF

Step-by-step explanation:

Let the height of 6th student be x.

Average = sum/total no.

Sum of heights of 6 students= Avg.× total no. of students

= 125×6

= 750.

now,

750 = 135+130+122+120+127+x

750=634+x

x= 750-634

x=116

Answer 2

$\huge \sf \red{answer}$To find average speed:-

$= > \bf{\frac{Total \: \: distance }{Total \: \: time} }$

$\bf{= > \frac{650 + 850}{12 + 18} }$

$\bf{ = > \frac{1500}{30} = 50kmph}$

So average speed is 50 kmph.
