Question

A car Travels at 90 kilometre per hour how much distance does it cover in 8 seconds​

Answer 1

Answer:

200m

Step-by-step explanation:

Speed = 90km/hr

Since time is given in seconds we have to convert the speed to m/s

1 kmph = 5/18 m/s

= 90 × 5/18 = 25 m/s

Speed = Distance / Time

They are asking distance so,

Distance = Speed × Time

= 25 × 8

= 200 m

Answer 2

Answer:

distance = 200 m

Step-by-step explanation:

given speed =90 km/h

as the time and distance is in terms of meters and seconds respectively, we must convert the speed to m/s

conversion factor=>   1   km/h  =  (km/h×5/18)   m/s

90 km/h = 90×5/18

               =25 m/s

time taken = 8 s

total distance covered is given by the product of speed and time [ as speed=distance / time ]

S=vt

 =25×8

  =200 m

therefore, the total distance covered = 200 m

hope it helped :)
