The answer is -40 because 1/2 of 4 is 2 and 1/2 of 5 is 2.5, 2•2.5=5. -2•-2•-2=-8. 5•-8=-40
Hey there! :)
There are 3 pennies
There is a total of 18 coins; 3 + 5 + 4 + 6 = 18
3 ÷ 18 = 0.16666666667 = 0.17
Your answer is 1/6 or 0.17
Hope this helps :)
Answer:
It will take them 5 hours to meet if they start moving towards eachother simultaneusly.
Step-by-step explanation:
Distance, s = 540 miles
Motocycle's speed, v = 48 mph
Time for motorcycle to cover 48 miles, t = 
=
= 11.25 h
For a car it takes 2.25 hours less than 11.25 for motorcycle:
Time for car than becomes: 11.25 - 2.25 = 9 h
Speed for car would be v(c) = 
=
= 60 mph
<em>For finding when they will meet, we will need relative speed: </em>
Since they are moving towards each other the relative speed is the sum of speed of car and the speed of motorcycle
Relative Speed = 48 + 60 = 108 mph
Distance = 540 miles
Time = 
= 
= 5 hours
