Answer 2

$\huge \mid{ \underline{ \overline{ \underline{\overline \pink{\bold{ \: \: Aɴsᴡᴇʀ \: \: } }}} }}\mid$

• distance = 400 km
• time taken = 5 hours
• speed = ?

$speed = \frac{distance}{time} \\ \\ \implies speed = \cancel \frac{400}{5} \: \: \: \: \: \: \: \: \: \: \\ \\ \implies speed = 80 \: km {h}^{ - 1}$

so, average speed of the car is 80 km/hr
