Answer:

Step-by-step explanation:

Given:

L = 68 km

V₁ = 88.2 km/h

V₂ = 97.4 km/h

_____________

t -?

Time to complete the distance for each skier:

t₁ = L / V₁ = 68 / 88.2 ≈ 0.77 h

t₂ = L / V₂ = 68 / 97.4 ≈ 0.70 h

Waiting time:

t = t₁ - t₂ = 0.77 - 0.70 = 0.07 h

or

t = 60·0.07 = 4.2 min
