The exponential equation of the model is A(t) = 2583 * 0.88^t and the multiplier means that the number of new cases in a week is 88% of the previous week
<h3>The function that models the data</h3>
The given parameters are:
New, A(t) = 2000
Rate, r = 12%
The function is represented as:
A(t) = A * (1 - r)^t
So, we have:
2000 = A * (1 - 12%)^t
This gives
2000 = A * (0.88)^t
2 weeks ago implies that;
t = 2
So, we have:
2000 = A * 0.88^2
Evaluate
2000 = A * 0.7744
Divide by 0.7744
A = 2583
Substitute A = 2583 in A(t) = A * 0.88^t
A(t) = 2583 * 0.88^t
Hence, the exponential equation of the model is A(t) = 2583 * 0.88^t
<h3>The interpretation of the multiplier</h3>
In this case, the multiplier is 88% or 0.88
This means that the number of new cases in a week is 88% of the previous week

Answer:
40 min is the answer
Step-by-step explanation:
To solve this we need to convert all the units into SI units
for ritu,
speed= 90km/hr
= 90 × 1km/ 1hour
= 90×1000/3600 m/s
= 25m/s
distance = 120×1000m
time = distance/ speed
= 120000/25
= 4800sec
= 4800/60min
= 80 min
for garima,
distance =120×1000m
speed = 60km/hr
= 60×1000/3600 m/s
=100/6 m/
time = 120000/(100÷6)
= 7200sec
= 7200÷60 min
= 120 min
time difference is 120-80 = 40 min
