1500m=1.5km so 1500 divided by 10= 150s it takes 150s to cover a distance of 1.5km
Answer:
Distance swam by Sonya in 3 weeks = 19740 m
Step-by-step explanation:
To practice for a competition, Sonya swam 0.94 kilometer in the pool each day for 3 weeks.
Number of days in 1 week = 7
Number of weeks she swam = 3
Total number of days she swam = 3 x 7 = 21 days
Distance swam per day = 0.94 km
Total distance swam = Total number of days she swam x Distance swam per day
Total distance swam = 21 x 0.94 = 19.74 km = 19.74 x 1000 m = 19740 m
Distance swam by Sonya in 3 weeks = 19740 m
Step-by-step explanation:
3a^2+24a+45=0
×3/3( first ×3)
9a^2+24(3a)+135=0
(3a+15)(3a+9)=0
now /3
3(a+5)(a+3)
a=-5✓
a=-3✓
