If a car travels 400m in 20 seconds how fast is it going?

Answer 1

ydefk

Answer 2

400 meters in 20 secs 1.6km in 80 secs, or 1 mile in 80 seconds. This is somewhere around 50-53 mph.

Answer 3

400m/20s reducing it gives us,

= 20m/1s to convert to km/h we do,

203600/11000 we did 20*3600 because with time distnace will increase and 3600 seconds makes an hour 3600/1000=3.6,

so we basically do 20*3.6 we get,= 72kmph

Answer 4

To determine the speed of the car, we can use the formula:

Speed = Distance ÷ Time

Here, the distance travelled by the car is 400m and the time taken is 20 seconds. Plugging these values into the formula, we get:

Speed = 400m ÷ 20s

Speed = 20m/s

Therefore, the car is travelling at a speed of 20 meters per second (or approximately 72 kilometers per hour).

Answer 5

To calculate the speed of the car, you need to divide the distance it has traveled by the time it took to travel that distance. In this case, the car has traveled a distance of 400 meters in 20 seconds.

Speed = Distance / Time

Speed = 400 meters / 20 seconds

Speed = 20 meters/second

So the car is going 20 meters/second or 20 m/s.

Speed doesn't take direction into account.

Answer 6

speed = distance/time = 400m / 20s = 20 m/s

If you want it in mph:

3600 s = 1 hr

1609.344 m = 1 mile

→ 20 m/s = 20 × 3600 m/hr = 20 × 3600 ÷ 1609.344 mph ≈ 44.7 mph

Answer 7

If the car travels 400m in 20sec, the it is moving with a speed of 400m/20sec i.e, 20m/sec.

Answer 8

The car would be travelling at 72 Kilometres per hour...

i.e. 3 x 400 in 1 minute x 60 in 1 hour - 72000 metres per hour.

Or 44.7387258 miles per hour.

Answer 9

20 miles per second because you divide meters by seconds then round if nessasary ,but in this case you did not need to so the answer was 20 then you have to add your units
