Answer 1

Question :

A car travels at a speed of 55 km/h. Find the distance travelled by the car in 12 minutes 30 sec, giving your answer in metres.

ㅤㅤㅤㅤㅤ

Solution :

ㅤㅤㅤㅤㅤ

Speed of car = 55km/hr

Convert it into m/sec:

$: \implies \tt { 55 \times \dfrac {5}{18} }$

ㅤㅤㅤㅤㅤ

Time taken by car = 12min 30 sec.

convert it into seconds :

$: \implies \tt { 12 \times 60 + 30 = 750 \: seconds }$

ㅤㅤㅤㅤㅤ

$\boxed {\bf Speed \: = \dfrac {Distance }{Time}}$

ㅤㅤㅤㅤㅤ

$\boxed {\boxed {\bf Distance \: = speed \times time }}$

ㅤㅤㅤㅤㅤ

$: \implies \tt { Distance = 55 \times \dfrac {5}{18} \times 750}$

ㅤㅤㅤㅤㅤ

$: \implies \tt { Distance = 11458.3 m }$
