Answer:
48 miles per hour
Step-by-step explanation:
If they traveled 2400 miles and the total driving time was 50 hours, divide 2400/50 in order to find how many miles they drove per hour.
The first one is 2 the second one is 3
Billy drove 3.75 miles. You find the answer by dividing 7.5 by 2
Answer:
s cubed
Step-by-step explanation:
bc volume is length times width times height so it would be s times s times s which is s cubed
Joel = j, Mark = m, Sandra = s
j + m + s = 120
m = 3j
j = 1/2 s --> s = 2j
plug in (substitute) each letter to make it in terms of only j: j + m + s = 120
j + 3j + 2j = 120
6j = 120
6j/6 = 120/6
j = 20
now plug in for the j & s equation:
s = 2j = 2(20) = 40
Therefore Sandra has 40 coins!
