4*25= 100 (total points)
x + y = 24 4x-2y = 66
since he only answered 24 questions
therefore max he can get is 96
x + y = 24
4x-2y = 66 from first equation,
y = 24-x plug that in second equation :
4x - 2(24-x) = 66
4x - 48 + 2x = 66
6x = 114
x = 19
Answer:
6hrs
Step-by-step explanation:
Speed = distance/time
Given
Speed = 60mph and
Distance = 360 miles
Therefore
60 = 360/time
Cross multiply
time x 60 = 360
Divide both sides by 60
time x 60/60 = 360/60
time = 6 hrs
