Answer 2

${\purple{\underline{\underline{\bf{\pink{Solution:-}}}}}}$

$\mathfrak{\underline{AnswEr:-}}$

• The total distance covered by the car in these 30 minutes = 25 km

$\mathfrak{\underline{Given:-}}$

• A car moves with the speed of 40 km/hour for 15 minutes and then with a speed of 60 km/hour in the next 15 minutes.

$\mathfrak{\underline{Need\:To\: Find:-}}$

• The total distance covered by the car in these 30 minutes = ?

${\purple{\underline{\underline{\bf{\pink{Explanation:-}}}}}}$

1st Distance:

• Speed = 40km/hour

• Time = 15 minutes

• Time = $\mathsf {\dfrac{\cancel{15}}{\cancel{60}}\:}$

• Time = $\mathsf {\dfrac{1}{4}\:hour}$

$\:\:\:\:\dag\bf{\underline \green{Formula\:used\:here:-}}$

$\bigstar{\underline{\boxed{\sf\purple{Distance = Speed \times Time}}}}$

$\:\:\:\:\dag\bf{\underline \blue{Putting\:the\:values:-}}$

$\longrightarrow \sf {Distance = 40 \times \dfrac{1}{4}}$

$\longrightarrow \sf {Distance = 10\:km}$

$\rule{200}{2}$

2nd Distance:

• Speed = 60km/hour

• Time = 15 minutes

• Time = $\mathsf {\dfrac{1}{4}\:hour}$

$\:\:\:\:\dag\bf{\underline \green{Formula\:used\:here:-}}$

$\bigstar{\underline{\boxed{\sf\purple{Distance = Speed \times Time}}}}$

$\:\:\:\:\dag\bf{\underline \blue{Putting\:the\:values:-}}$

$\longrightarrow \sf {Distance = 60 \times \dfrac{1}{4}}$

$\longrightarrow \sf {Distance = 15\:km}$

$\rule{200}{2}$

$\:\:\:\:\dag\bf{\underline \green{As\:we\:know\:that:-}}$

$\bigstar{\underline{\boxed{\sf\purple{1st \: distance + 2nd\: distance}}}}$

$\longrightarrow \sf {Total \:distance = 15 + 10}$

$\longrightarrow \sf {Total\: distance = 25\:km}$

$\:\:\:\:\dag\bf{\underline{\underline \blue{Hence:-}}}$

• The total distance covered by the car in these 30 minutes = 25 km

$\rule{200}{2}$
