Answer:
12.5 m
Step-by-step explanation:
recall that 1 km = 1000 m
hence 90 km/h is equivalent to 90 km/h x 1000 m/km = 90,000 m/hr
also recall that 1 hour = 60 x 60 = 3600 s
hence 90,000 m/hr is equivalent to 90,000 m/hr x (1/3600) hr/s = 25 m/s.
given that is eyes were closed for 0.5 s.
in 0.5s, he travelled :
0.5s x 25 m/s = 12.5 m
Answer:
1.2km is 400% of 300m
Step-by-step explanation:
1 km=1000m
So,1.2 km=1000*1.2=1200m
Let 1.2km(or 1200m) be x% of 300 m
By the problem,
300*x/100 = 1200
Or, 3x=1200
Or,x=1200/3=400
1.2km is 400% of 300m
