4,3 and 1,0 that’s the answer
<span>So basically you drove 1/2 hour at 100 km/h which works out to a total travel distance of 50 km (you multiply a 1/2 by 100)
Then you drove for 3/4 hour at 80 Km/h which works out to a total travel distance of 60 km (multiply 3/4 by 80)
now you know that you traveled a total of 110 km
now add up all the times 30 + 15 + 45 = 90 minutes or 1.5 hours
now you know that you traveled a total of 110 km in 1.5 hours
so your average speed is 73.33 km/h for the entire trip</span>
Is this a multi question ? If so
Please post full question to get full answer
Thank You :)
Two angles are complementary: x + y = 90 (complementary = 90 degrees)
x = 2y
plug in 2y for x
2y + y = 90
3y = 90
3y/3 = 90/3
y = 30
plug in 30 for y
x = 2y
x = 2(30)
x = 60
x (the largest angle) = 60°
hope this helps
