Question

A person travelled 30km at 5 km/hr and again 16 km at4 km/hr. The average speed km/hr is

Answer 1

Answer:

Therefore Speed= \dfrac{Distance}{Time}  which implies:

Distance = Speed \times Time  

Time = \dfrac{Distance}{Speed}

Step-by-step explanation:Therefore Speed= \dfrac{Distance}{Time}  which implies:

Distance = Speed \times Time  

Time = \dfrac{Distance}{Speed}

Answer 2

Step-by-step explanation:

speed = distance/time

time = distance/speed

30km at 5kmph,

let time taken = t1 = 30/5=6hrs

16 km at 4kmph,

let time = t2 = 16/4=4hrs

total distance =30+16=46km

total time = 4+6=10hrs

speed = 46/10= 4.6kmph
