Answer: C 75
Step-by-step explanation: time to distance is ratio 4:5 = 60:X
In 1min He walks 5/4
in 60mins He walks 5/4 ×60
We are given that the insect can lift 1.182 x 10^3 times
it's own weight. Say that w is weight, so the lift is:
lift = 1.182 x 10^3 * w
Assuming that your body weight is 60 kg, therefore you
can lift:
lift = 1.182 x 10^3 * 60 kg = 70,920 kg
Student Tickets - x-64
Adult Tickets - x
x+x-64=386
2x=450
x=225
225 adult tickets were sold,
161 student tickets were sold.
Hope that helps!
