I looked it up and it gave me educational exercise, but I don't know if it is right.
I've had a similar question on an assignment myself, so I'm going to assume it had the same idea.

Hope this helps!
Answer:
72 m
Explanation:
Given:
v₀ = 0 m/s
v = 60 m/s
a = 25 m/s²
Find: Δx
v² = v₀² + 2aΔx
(60 m/s)² = (0 m/s)² + 2 (25 m/s²) Δx
Δx = 72 m
