the group covered the first 70 miles in 10 hours. then it doubled its paceto travel 280 miles. how long did it takethe group to travel 350 miles?
70 mi/h and 140mi/h
35070 = 280
280 miles left, 140 miles every 10 hours
so 20 hours
20hrs + 10hrs = 30 hrs
it took the group 30 hours to travel 350 miles
sorry, not 1, +1
