1 hour = 60 minutes
0.4 hours = 60 x 0.4 = 24
Time = Distance/Speed = 500/64 = 7.8125 hours = 7 hours 48 min 45 sec.

Copper-64 (Cu-64) has a half-life of approximately 12.7 hours. After one half-life (12.7 hours), half of the original sample would remain. Therefore, from a 2 mg sample, after 12 hours, approximately 1 mg of Cu-64 would remain, as it has not yet fully completed one full half-life.
0.7 hours = 42 minutes.

To calculate the time it takes to drive 64 miles at a speed of 80 miles per hour, you can use the formula: time = distance ÷ speed. Plugging in the values, time = 64 miles ÷ 80 miles per hour, which equals 0.8 hours. Converting 0.8 hours to minutes gives you 48 minutes. Therefore, it will take approximately 48 minutes to drive 64 miles at that speed.
Exactly eight times !
