If will drives 30 mph for 1.5 hours and then 40 mph for 2 hours, then how far did he drive?

We know the formula for rate is distance / time.

So The formula for distance shall be rate × time

Distance = rate × time.

Rate = 30 mph, Time = 1.5 h

Distance = 30 × 1.5 = 45 miles

Also for the second leg of the journey

Rate = 40 mph and time = 2 hours

Distance = 40 × 2 = 80 miles.

Total distance traveled = 45 + 80 = 125 miles

If Will drives 30 mph for 1.5 hours and then 40 mph for 2 hours, then he shall drive 125 miles.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

answer: i think it is (1,-2)
