Question

How do I complete this question?

Answer 1

4 months

Explanation:

Equation for Charles City:

where l is total length and t is time in months.

`l = 5 * 2^t^-^1` because the total length doubles every month, except the first month where the original path length was 5km

Equation for Tinsel Town:

`l = 21 + 5(t-1)` because the total length increases by 5km per month and it started at 21 km. The length will not increase for the first month.

At 1 month: CC length = 5 km

TT length = 21 km

At 2 months: CC length = 10 km

TT length = 26 km

At 3 months: CC length = 20 km

TT length = 31 km

At 4 months: CC length = 40 km

TT length = 35 km

So, Charles City's total path length wil bypass that of Tinsel Town in 4 months.
