$\large \bold {ANSWER}$

➢ The average speed of the car is 15 km/h and 4.166 m/s.

$\large \bold {SOLUTION}$

$\Large \text { \sf v = \dfrac {45}{3} = 15 km/h }$

$\Large \text { \sf\dfrac {15km/h}{3,6} = 4,166m/s }$

Answer 2

Answer: 15 km/h, 4.16 m/s

Step-by-Step Explanation:

Distance (D) = 45 km
Time (T) = 3 hours

Average Speed (S) = D/T

Speed in km/h = 45/3 = 15 km/h
Speed in m/s = 15 * (5/18) = 4.16 m/s
