First correct answer will be brainlisted

Answer 1

Explanation:

the car travels 42Kms in 35 mins

Answer 2

→ (d) speed between $\sf 11:25 am$ and $\sf 11:40 am$

So, now we know that formula which gives us speed

$\sf \implies speed \: \: = \frac{v_{2} - v _{1}}{time} = \frac{m}{ {s}^{2} }$

Where $\sf V_1 = 38 km = 38,000 m$

$→ \sf V_2 = 42 km = 42,000 m$

$→ \sf time = 11:40 - 11:25 = 15 min = 900 sec$

$\sf \implies speed \: \: = \frac{v_{2} - v _{1}}{time} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf \implies \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{42000 - 38000}{900} \\ \\ \sf \implies \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{40 \cancel{00}}{9 \cancel{00}} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf \implies \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{40}{9} \: \frac{m}{ {s}^{2} } \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf \implies \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \red{4.44 \:m/ {s}^{2} } \: \: \: \: \: \: \: \: \: \:$
