Answer:
Tina's average speed for the whole journey = 56 kmph
Step-by-step explanation:
Time taken by Sean to travel from Town A to Town B = 4 hours.
Average speed of Sean = 70 km/h
We have equation of motion, s = ut + 0.5 at²
Time, t = 4 hours.
Initial speed, u = 70 km/hr
Acceleration, a = 0 m/s²
Substituting
s = ut + 0.5 at²
s = 70 x 4 + 0.5 x 0 x 4²
s = 280 km
Distance from Town A to Town B = 280 km
Tina took 1 hour more than Sean.
Time taken by Tina to travel from Town A to Town B = 4 +1 = 5 hours
We have equation of motion, s = ut + 0.5 at²
Time, t = 5 hours.
Displacement, s = 280 km
Acceleration, a = 0 m/s²
Substituting
s = ut + 0.5 at²
280 = u x 5 + 0.5 x 0 x 5²
u = 56 km/hr
Tina's average speed for the whole journey = 56 kmph
Answer:
y = 2
Step-by-step explanation:
Kindly view the attached image to see the rules when looking for the horizontal asymptote.
In this situation we have 2x² / x²
The powers of both are equal to each other therefore the horizontal asymptote will be at the coefficient of the numerator divided by the coefficient of the denominator.
In other words the horizontal asymptote is at y = 2/1 or just 2
Answer:
Your answer is Taylor
Step-by-step explanation:
<span>1. </span><span>The answer is letter b. four more
than twice a number.
Given number = 2n + 4,
=> 2n = twice a number, n represents the unknown number
=> + = add or more than
=> 4 = four
So, this can be say as = twice a number more than 4 , or four more than twice a
number.
Thus, the given equation’s answer is letter B. four more than twice a number
=> Four = 4
=> more than = +
=> twice a number = 2n
=> 4 + 2n, the same as 2n + 4</span>
