5. total time taken = 3hrs

speed = 30km/hr

total distance travelled = 30 * 3= 90km

6. total time taken = 1.5hrs = 1 1/2 hrs

speed = 70 miles/hr

distance travelled in 1/2 hrs = 1/2 * 70 = 35 miles

total distance travelled = 3/2 * 70 = 3 * 35 = 105 miles

Rest of the answer jen will help

Hey, guys help me answer!

Hello and Good Morning/Afternoon

Let's take this problem step by step.

$5=\frac{1}{3}(5x-15)\\ 5=\frac{5}{3}x-5\\ 5+5= \frac{5}{3}x-5 +5\\10=\frac{5}{3}x\\ 10 * 3 = 3* \frac{5}{3}x\\30=5x\\\frac{30}{5} =\frac{5}{5}x\\ 6=x\\x=6$

What did we do in this problem

we ensured that both sides remained equally balanced in value
took everything step-by-step to make sure that there were no mistakes
to check it, we can plug it back into the original equation to see if it works

$5=\frac{1}{3}(5(6)-15)\\ 5=\frac{1}{3} (30-15)\\5=\frac{1}{3}*15\\ 5=5 \checkmark\\$

Answer: x = 6

Hope that helps!
