Question

two cars A and B
are moving with average speed of 40 km per hour and 50 km per hour respectively in the same direction find how far will ka be be form ka a after 3 hours
​

Answer 1

Answer:

Speed of Car A = 40 km/hr

Speed of Car B = 50 km/hr

Distance travelled by Car A in 3 hours:

= 40 × 3 = 120 km

Distance travelled by Car B in 3 hours:

= 50 × 3 = 150 km

Thus, after three hours Car A will be 150 - 120 = 30 km far from Car B.

Answer 2

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

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

• After 3 hours Car A will be 30 km far from Car B.

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

• Two cars A and B, are moving with average speeds of 40 km/hour and 50 km/hour, respectively, in the same direction.

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

• How far will car B be form car A after 3 hours = ?

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

Distance covered by car A in 3 hours,

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

$\star\large{\boxed{\sf\red{Distance = Speed \times Time }}}$

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

$\longrightarrow \sf {Distance\:covered\:by\:car\:A = 40 \times 30}$

$\longrightarrow \sf {Distance\:covered\:by\:car\:A = 120\:km}$

$\rule{300}{2}$

Distance covered by Car B in 3 hours,

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

$\star\large{\boxed{\sf\red{Distance = Speed \times Time }}}$

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

$\longrightarrow \sf {Distance\:covered\:by\:car\:B = 50 \times 3}$

$\longrightarrow \sf {Distance\:covered\:by\:car\:B = 150\:km}$

$\rule{300}{2}$

Distance between car A and car B after 3 hours,

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

$\star\large{\boxed{\sf\red{Distance\:covered\:by\:car\:A - Distance\: covered \:by\:Car\:B }}}$

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

$\longrightarrow \sf {Distance\: between\:car\: And\:car\:B = 150\:km - 120\:km}$

$\longrightarrow \sf {Distance\: between\:car\: And\:car\:B =30\:km}$

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

• After 3 hours Car A will be 30 km far from Car B.

$\rule{300}{2}$
