Answer 2

Calculating the speed of the second car

The first car travelled a distance in 30 seconds with a speed of 72 km/h. To calculate the distance travelled: * Speed = 72 km/h = 20 m/s (kilometers per hour to meters per second conversion) * Time = 30 s * Using the formula: Distance = Speed x Time * Distance = 20 m/s x 30 s = 600 m

The second car travelled the same distance in 40 seconds. To calculate its speed: * Distance = 600 m (given to be the same as the first car) * Time = 40 s * Using the formula: Speed = Distance / Time * Speed = 600 m / 40 s = 15 m/s * Converting meters/second to km/h: Speed = 15 m/s x 3.6 = 54 km/h

Therefore, the speed of the second car was 54 km/h.
