Answer 1

To solve this we first of all need to find the distances travelled by both Vaimiti and Jabril and then we will find their difference...

Let's start solving ~

Distance covered by Vaimiti ⤵️

$\tt \leadsto \: Distance = Speed × Time$

Vaimiti's speed = 1.1 m/s

Time taken by her = 25 minutes = 25×60 = 1500 seconds

$\sf \leadsto \: Distance = 1.1 \times 1500$

$\boxed{ \rm\multimap \: Distance = 1650 \: m}$

$\red{ \rule{35pt}{2pt}} \orange{ \rule{35pt}{2pt}} \color{yellow}{ \rule{35pt} {2pt}} \green{ \rule{35pt} {2pt}} \blue{ \rule{35pt} {2pt}} \purple{ \rule{35pt} {2pt}}$

Distance covered by Jabril ⤵️

$\tt \leadsto \: Distance = Speed × Time$

Jabril's speed = 1.3 m/s

Time taken by her = 30 minutes = 30×60 = 1800 seconds

$\sf \leadsto \: Distance = 1.3\times 1800$

$\boxed{ \rm\multimap \: Distance = 2340 \: m}$

$\rule{300pt}{3pt}$

Difference between distances travelled by them↯

Distance travelled by Vaimiti = 1650 m

Distance travelled by Jabril = 2340 m

$\bf\nRightarrow \: Difference = 2340 - 1650$

$\bf \nRightarrow \: Difference = 690 \: m$

➪ Therefore, The difference between distance travelled by them is 690 meter...~
