Question

in 5 seconds the car will cover 100 meters . how many meters it covers in 20 secondss​

Answer 1

Answer:

1 m/s = 2.23693629 mph.

so, 100m / 10 sec = 10 m/s = 22..37 mph.

alternatively:

100m /10 sec = 10 m/s = (10 m/s) (60 s/min) (60 min/h) =36,000 m/h = 36 km/hr

Note that the units operate just as the numbers operate in the equations.

Explanation:

or

Distance covered= S= 100m

Time= t= 10sec

As

Speed = Distance/time= S/t

Speed= 100/10

Speed= 10m/sec

Speed= 10 x 60 m/min

Speed= 10 x 60 x 60 m/hour

Speed= 36,000m/hour

or

Speed= 36Km/hour
