1000/70=100/7=14.28 hours 14 hours 17.14 minutes
so there will be 14 hours of driving
3 6 9 12
S = �(2*30 + 15(3))4
S = 210
210 3 +30
420 6 +45
630 9 +60
840 12 +75
120 2
20 17.14
1000-840=160 miles
160-140=20 miles
20/70=2/7*60=17.14 minutes
14h 17.14
210 minutes=3 hours 30 minutes
17 hours 47.14 minutes
