Question

Ajay walked at an average speed of 8km/hr. For 45mint and then run at 12km/hr. For 40mint. What was his average speed for the whole journey

Answer 1

Answer:

Explanation:

Total distance covered in first 45 minutes,

He travels at 8kmph.That is 8 km per 60 minutes...So, for first 45 minutes,he travelled 8km * 45 minutes divided by 60 minutes

which gives us 6!

(Hint : Formula : distance = speed * time

Here,speed is 8/60 and time is 45

So, 8/60*45 or 8*45/60)

So,Ajay covered 6kms in first 45 minutes

And then he runs at 12kmph for 40 minutes

So,in 40 minutes,he covered

Distance = 12/60 * 40

= 8 km

So,first ajay covered 6 kms and then he covered 8 kms

In total,Ajay covered 14 kms.
