Speed = distance / time
Speed = ?
Distance = 350km
Time = 5 hours
350km / 5hours = 70
He averages 70km/h
Well, let's see. First we would need to find how much money he earns each DAY. To find THAT, we would need to multiply 760 times 1.5, which would be $1,140. Now, in order to find out how many DAYS it will take to make $3,420, you would divide 3,420 divided by 1,140, which will be 3. So it will take 3 days to earn $3,420.
I hope I helped! =D
Use FOIL to multiply binomials by multiplying each term in the first binomial by the terms in the second binomial.
(4x - 3)(x + 5)
4x^2+20x-3x-15
Now combine like terms.
answer : 4x^2+17x-15
