To solve this problem, let us first assign some variables.
Let us say that:
v1 = velocity of airplane = 180 mph
t1 = time travelled by airplane
v2 = velocity of jet = 330 mph
t2 = time travelled by jet
Since we know that distance is the product of velocity and
time, and that the distance travelled by the two must be equal for the jet to
catch up to the plane, hence:
v1 * t1 = v2 * t2
But we know that:
t1 = t2 + 1
Therefore:
180 (t2 + 1) = 330 t2
180 t2 + 180 = 330 t2
150 t2 = 180
t2 = 1.2 hours
<span>Therefore the jet can catch up to the plane after 1.2
hours it takes off.</span>

so.. what value of "x" makes x+4 to 0?
the domain will be, all real numbers, except that value
about the range, "y" will take, whateve "x" can provide.. in this case... I think is all real numbers, except 0, because, if you give a few big values to "x", the fraction will simply have a bigger and bigger denominator, making the fraction smaller and smaller, ever approaching 0, but never getting there
Answer:
$7.25
Step-by-step explanation:
First hour=3.50
still have 1 1/2 hours left =3 half hours
1.25x 3=3.75
3.50+3.75=7.25
Answer:
speed = distance / time
At 96miles in 2 hours
the speed = 96miles/ 2hours = 48miles per hour
at 5 hours, Distance = speed x time
distance = 48 x 5 = 240miles
Step-by-step explanation:
step 1 : determine the speed per hour
speed = distance / time
step 2 : after getting the speed of the car per hour, the distance cover in 5hours can now be determine using
distance = speed x time
