Question

a moter cyclists drives from point a to be with a uniform speed 30km/h and returns with s speed of 20km/h. find nits average speed.​

Answer 1

Answer:

HEY THERE!! HERE IS YOUR ANSWER  

Explanation:

Let the distance between those two points be d

Speed1 = 30km/h

Time 1 = distance / speed

= d/30 h

Speed while returning = 20km

Time 2 = d/20 h

Average speed = total distance covered / total time taken

=( d+d) ÷ (d/20) +(d/30)

= 2d ÷ (3d+2d) / 60

= (12)(2)

= 24

So, the average speed was 24 km/h.
