At start Keenan has x strawberries. He gives Tisha x/2. Then Tisha keeps 4 strawberries and gives Suvi the rest. If y is the number of strawberries that Suvi gets:
y = x/2 - 4.
For example: Keenan has 20 strawberries. He gives Tisha 10 and Tisha gives Suvi 6:
6 = 20/2 - 4
6 = 10 - 4
in 20 days 4 half life will be completed
so n = 4
formula :-

<span>Time = Distance/Speed
Time = 153/70
Time = 2.19 hours.
Time = 2 hours 11 minutes.
Hope this helps.
