Answer:
0.12h (approx.)
Explanation:
(Note: If the mph stands for miles per hour)
Given that: Initial Velocity (u) = 0mph
Final Velocity (v) = 203mph
Distance (s) = 12.42miles
Time (t) = ?
Using the first equation of motion:
S={(v+u)÷2}×t
12.42={(203+0)÷2}×t
12.42={203÷2}×t
12.42={101.5}×t
12.42={101.5}t
t=12.42÷101.5
t=0.122364532h
t=0.12h (approximately)
