Step-by-step explanation:
Answer:
about 3 1/2 hours long
Step-by-step explanation:
70 goes into 240 evenly 3 times, and 70×3 equals 210. that leaves 30 miles remaining. since he is moving at an average rate of 70mph, 3/7 would be the remaining time. to decimal that equals a total of about 3 hours and 25 minutes, which, rounded up, equals 3 and 1 half hours.
3k-1=7k+2
+1 +1
3k=7k+3
-7k -7k
-4k=3
divide each side by -4
/-4 /-4
k=-3/4
or
k=-.75
