-- Driving at 30 mph for 20 minutes (1/3 hour), you cover 10 miles.
-- Walking at 3 mph for 10 minutes (1/6 hour), you cover 0.5 mile.
-- Average speed = (total distance covered) / (time to cover the distance)
= (10.5 miles) / ( 1/2 hour)
= 21 miles per hour.
When I did the math in my head the fraction I got was 20/100000. 20/100000 as a decimal form is 0.0002.
Step-by-step explanation:
mean score means the sum of all 6 scores divided by the number of games : 6.
sum6/6 = 15
sum6 = 15×6 = 90
(sum6 + x)/7 = 16
sum6 + x = 16×7 = 112
90 + x = 112
x = 22
they scored 22 points in the 7th game.
Answer: y=5, x=4
Step-by-step explanation:
3y= 15 divide both sides by 3
Y= 5
4x = x+12 subtract x from both sides.
3x = 12 divide both sides by 3
X= 4
