Question

A car takes 3h to cover a distance of 60 km. Calculate its speed in km/h and m/s.​

Answer 1

Answer:

d=60km

Let's consider the total time taken to cover the distance is t.

If half of the total time traveled with speed 80km/h,

d1=80×2t=40t

Rest half time is covered with speed 40km/h, 

d2=40×2t=20t

The average speed of the car is Total distance covered by the car divided total time,

vavg=td1+d2

vavg=t40t+20t=t60t

vavg=60km/h

Answer 2

Answer:

This is the answer
