Answer 2

${ \underline{ \underline{ Answer = 214.28km {hr}^{ - 1} }}}$

Here

Total time travelled by car = 14min

convert 14 min into hr =

$14 \: min \: = \frac{14}{60} \: hr$

Total distance travelled by car = 10 + 18 + 7 + 15 = 50 km

$speed \: = \frac{distance}{time} \\ \\ speed = \frac{50 \times 60}{35} = 214.28 \\ \\ average \: speed \: = 214.28 \: km \: {hr}^{ - 1}$

✌️Hope this will helps you ✌️
