Step-by-step explanation:
Speed = 90Km/h =90x100/60x60 = 90000/3600 = 25m/s
time = 20s
Distance ?
Speed = total distance travelled/time taken
From the angle of change of formula thereby making distance traveled the subject formula
Therefore, Distance traveled = speed X time taken
===> Distance traveled = 25 x 20
The car will cover a distance of 500m

Answer:
1 hour = 3600 seconds
90 km = 90,000 m
20/3600 = 1/180
90,000m * 1/180 = 500m
The car will travel 0.5 km in 20 seconds
Check:
20sec * 3 = 1min
0.5 * 3 = 1.5km/min
60min = 1hr
1.5km * 60min = 90km/hr
