Given:
The two cars met at t= 5 hours
Car A leaves at t=0
Car B leaves at t = 4.5 hours, so only traveled for only 0.5 hours.
Car B travels 150 kilometers
so d = distance from A to B
As a result, Car A travels d - 150 km
150 = (Vb) * (0.5) ---> time of travel which is 0.5 hours
divide both sides by 0.5, you'll get Vb = 300 km/h this is the speed of Car B
Va = Vb - 10km/hr
Va = 300 - 10km/hr
Va = 290 km/hr is the speed of Car A
so:
d - 150 = (Va) * t
d - 150 = 290 * 5
d - 150 = 1450
d = 1450 + 150
d = 1600 km
The distance between Car A and Car B is 1600 kilometers.
Step-by-step explanation:
x^2 -2kx +7k -12 = 0
two equal roots -->Δ = b^2 -4ac = 4k^2 - 4(7k-12)=0 = 4(k^2 - 7k +12)=4(k-4)(k-3)=0
so k =3 and k =4
Answer:
1100 mm = 1.1 m, and 900 mm = 0.9 m.
So the area is 1.1 x 0.9 = 0.99 m^2
Answer:
The answer is A. The product is greater than 12
Answer:
You first need to know what number 6 4/5 is, which is 6.8. To figure it out, you multiply 6 by 5 then add 4 and put the number you get on top of the fraction so it would be 34/5 = 6.8
6.9 is the answer
6.9 is bigger than 6.8 and smaller than 7
