Wall side(a) fixed 4 kilometers
Another side(b) decreasing at the rate of 0.8 kilometers per minute
Speed on land(h) increasing at a rate of 0.6 kilometers per minute.
At a certain time, side(b) is 10kilometers and the h is 2 kilometers.
What is the rate of change in the area at that instant
a = 4 Km, b = 10 Km, h = 2Km, t = time
def TAcalc(a,b,h,bv,hv): """ a = wall side, b = another side at time t, h = tsunami length on land, bv = velocity of b, hv = velocity of h usage TAcalc(a,b,h,bv,hv) """ return 1/2*(a*hv + bv*h + b*hv) TAcalc(4,10,2,-0.8,0.6)
