Question

A scooter covers a distance in 4.5hours moving at a speed of 60km/ hr . How much should it increase its speed to cover the same distance in 4 hour?

Answer 1

Answer:

4.5+64+4=72.5

Step-by-step explanation:

Answer 2

Time = 4.5 hrs

Speed = 60km/h

Distance= s*t

= 60*4.5

= 270km

So we have to find Speed in same distance

S = d/t

= 270/4

= 67.5 km/h

So next we have to find the increase speed = 67.5 km/h - 60km/h

= 7.5 km/h
