Answer 1

Answer:

$\huge\bf\red{answer}$

Explanation:

Given

★ MOTORCYCLE TRAVEL A TO B

★AT A UNIFORM SPEED OF 30KM/H

★RETURN WITH A SPEED OF 20KM/H

★FIND AVERAGE SPEED =?

$\huge\bf{solution}$

• Total Distance from A to B = 30+20=50km/h

• distance of A(T1)= 30km/h (because uniform speed of motorcycle is 30km/h)

• distance of B (T2)= 20km/h ( because speed of bike is 20km/h)

• Average speed = total distance/total speed

=> A.V= (D+D)/(D/30+D/20)Km/h

=> A.V= 2×30×20/(30+20)km/h

=> A.V.= 1200/50km/h

=> A.V= 24km/h answer
