John will need to sleep for 10.3 hours before his second exam so that the
average of his two exam scores is an 80.
We were given
8 hours of sleep = 70
To get average of 80
<u>70+ x</u> = 80
2
Cross multiply:
70+x = 160
x= 160-70
= 90.
If 8 hours of sleep = 70
x hours of sleep = 90
Cross multiply
8× 90 = 70 × x
720 = 70x
x = 720/70
x = 10.2857
≈ 10.3 hours of sleep

Okay what is the question :)
Answer:
The final speed of bicycle would be <u>27 m/s</u>².
Step-by-step explanation:
<u>Given</u> :
Initial velocity (u) = 15 m/s
Acceleration (a) = 3.0 m/s²
Time = 4 seconds
<u>To</u><u> </u><u>Find</u> :
Final velocity (v)
<u>Using</u><u> </u><u>Formula</u> :

v = final velocity
u = initial velocity
a = acceleration
t = time taken
<u>Solution</u> :
Substituting the values in the formula to find the final velocity :







Hence, the final speed of bicycle would be 27 m/s².
