We have that, how long it will take for Liu to catch Mariel is mathematically given as

t=3.076s

From the question we are told

Mariel and Liu are running a long-distance race. Mariel runs at a rate of 5.4 m/s, and Liu runs at a rate of 7.6 m/s. If Mariel has a 20 m head start, how long will it take for Liu to catch Mariel?

Generally the equation for the Average speed is  mathematically given as

v_a=\frac{5.4+7.6}{2}\\\\V_a=6.5m/s

Therefore

How long it will take for Liu to catch Mariel is mathematically given as

t=\frac{20}{6.5}

t=3.076s

zimovet [89]
Apply the Pythagorean theorem

a^2 + b^2 = c^2

a = 5, b = 13.

5^2 = 25, 13^2 = 169

25 + 169 = 194

square root 194 = 13.928, rounded to nearest foot = 14 ft. 

The minimum ladder length required to reach the top of the wall = 14 ft.
