Total distance traveled = 4 + 6 = 10 miles
Total time = 15 + 25 = 40 minutes
Speed = 10 miles ÷ 40 minutes = 0.25 mph

Step-by-step explanation:
You can use the equation
fraction remaining = 0.5n where n is # of half lives elapsed
n = ?
fraction remaining = 1 - 0.612 = 0.388
0.388 = 0.5n
n = 1.37 = the # of half lives
1.37 x 5750 yrs = 7881 years
1x15=15 3x5=15 so 1 times 15 3x5=15
