Answer 1

Step-by-step explanation:

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} }:⟹55×

18

5

ㅤㅤㅤㅤㅤ

Time taken by car = 12min 30 sec.

convert it into seconds :

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

ㅤㅤㅤㅤㅤ

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

Speed=

Time

Distance

ㅤㅤㅤㅤㅤ

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

Distance=speed×time

ㅤㅤㅤㅤㅤ

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

18

5

×750

ㅤㅤㅤㅤㅤ

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