Answer 1

☞Given :-

A car covers 12 m in 4 secs and next 12 m in 2 sec.

☞To find :-

Calculate average speed.

￣￣￣￣￣￣￣￣￣￣￣￣

☞Formula used :-

$= \frac{total \: distance \: covered \: }{total \: time \: taken}$

￣￣￣￣￣￣￣￣￣￣￣￣

☞Solution :-

$average \: speed \: = \frac{total \: distance \: covered}{total \: time \: taken}$

$average \: speed = \frac{12 + 12m}{4 + 6s}$

$aveage \: speed \: = \frac{24 \: m}{6s}$

Average speed = 4 m/s .

Answer 2

Explanation:

☞Given :-

A car covers 12 m in 4 secs and next 12 m in 2 sec.

￣￣￣￣￣￣￣￣￣￣￣￣

☞To find :-

Calculate average speed.

￣￣￣￣￣￣￣￣￣￣￣￣

☞Formula used :-

= \frac{total \: distance \: covered \: }{total \: time \: taken} =

totaltimetaken

totaldistancecovered

￣￣￣￣￣￣￣￣￣￣￣￣

☞Solution :-

average \: speed \: = \frac{total \: distance \: covered}{total \: time \: taken} averagespeed=

totaltimetaken

totaldistancecovered

average \: speed = \frac{12 + 12m}{4 + 6s} averagespeed=

4+6s

12+12m

aveage \: speed \: = \frac{24 \: m}{6s} aveagespeed=

6s

24m

Average speed = 4 m/s .
