Answer:
6
Step-by-step explanation:
10 x 6 = 60
5 x 6 = 30
60 - 30 = 30
It will take 3 laps. 90*35=3150 1000 m = 1 km
$9 is discounted from the regular price. If you find the discounted price you get $21. Then subtract the 21 from 30 and you get 9
2/5 = 40%
3/10= 30%
1/2= 50%
1/10= 10%
so it's 1/2
First option because 3 x 10^9 is 3,000,000,000
