The speed of the vehicle in metres per second can be calculated as follows:
1.0 x 10² km/h = 100 km/h
1 km = 1000 m
100 km = 100,000 m
1 hour = 3600 seconds
Therefore:
100 km/h = 100,000 m/3600 s = 27.8 m/s
So, the speed of the vehicle in metres per second is 27.8 m/s.
1.0 x 10² km/h = 100 km/h
1 km = 1000 m
100 km = 100,000 m
1 hour = 3600 seconds
Therefore:
100 km/h = 100,000 m/3600 s = 27.8 m/s
So, the speed of the vehicle in metres per second is 27.8 m/s.

To find the distance the car traveled while the driver scanned the panel, we need to calculate the distance the car traveled in 1.5 seconds at a speed of 105 km/h.
First, we need to convert the speed from km/h to m/s:
105 km/h = (105 * 1000 m) / (60 * 60 s)
= 29.17 m/s
Next, we can use the formula:
distance = speed × time
distance = 29.17 m/s × 1.5 s
distance = 43.76 m
Therefore, the car traveled a distance of 43.76 meters while the driver scanned the instrument panel.
First, we need to convert the speed from km/h to m/s:
105 km/h = (105 * 1000 m) / (60 * 60 s)

distance = speed × time
distance = 29.17 m/s × 1.5 s
distance = 43.76 m
Therefore, the car traveled a distance of 43.76 meters while the driver scanned the instrument panel.
