Question

A train travels a distance with a speed of 30 km/h and returns with the speed of 50km/h . calculate average speex of the train​

Answer 1

hlooo there❤❤

your answer is here✌✌


Let the total distance be x
t = distance/speed
t1_x/30
t2_x/50
AVG speed = Total distance / total time
=x+x÷(x/30+x/50)
=2x÷5x+3x/150
=2x×150\8x
=150/4
=37.5km/h



Hope it's help you

Answer 2

Explanation:

Average speed = Total distance / total time taken

let the distance is =x

speed = 30km/h

time = distance / speed = x/30

Now, let the distance is = x

speed = 50

time = distance / speed = x/50

so use formula

Avg speed = total distance / total time

= x+x/x/30+x/50
