A colony of 1,000 bacteria doubles in size every 14 minutes. What will the population be 42 minutes from now?
bacteria

Nt = 2^n × No

Where Nt= No. Of cells at time t(for given time)

No= Initial no. Of cells (In your given case it's 10)

n = no. Of genarations

You can find ‘n' by using formula

n = t/g ….where g = generation time or doubling time for given bacteria .(in your given case it's 1 min.)

& t = given time

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
