Question

A car covered 500km in 3 hours 20 minutes. Find the speed in metre per second. how much distance will the car cover in 45 seconds.​

Answer 1

Answer:

speed is 41.66m/sec

and distance covered in 45 sec = 1.875 km or 1875 m

Step-by-step explanation:

x=u×t

x= distance,u=speed and t = time taken

500×1000 m= u×(30×60+20) ×60

u= [500×1000]÷12000 sec

   u=41.66 m/sec

again

         x=u×t

           x=41.66m/sec×45

        x=1875 meter   or 1.875 km

please mark as brilliant.

Answer 2

Answer:

Speed = 41.66m/s

Distance in 45 seconds = 1874.7m

Step-by-step explanation:

500km = 500000m

3 hours 20 minutes = 200minutes

200 minutes = 12000 seconds

Speed = distance / time

= 500000/12000

= 500/12

= 41.66m/s

distance will the car cover in 45 seconds:-

41.66 × 45

1874.7m
