In 5 seconds the car will cover 100 meters . how many meters it covers in 20 secondss |
|
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/hrNote that the UNITS OPERATE just as the numbers operate in the equations.Explanation:orDistance covered= S= 100mTime= t= 10secAsSpeed = Distance/time= S/tSpeed= 100/10Speed= 10m/secSpeed= 10 X 60 m/minSpeed= 10 x 60 x 60 m/hourSpeed= 36,000m/hourorSpeed= 36Km/hour |
