Answer:
At time t hours,
D(t) = √(5200t²)
Step-by-step explanation:
Charlies car is travelling at 40 miles/h while andy's car is travelling at 60 miles/h.
Now, distance = speed x time
Thus;
At a time t, the distance, covered by Charlie's car will be;
D1 = 40t
Similarly, At a time t, the distance, covered by Andy's car will be;
D2 = 60t
Using Pythagoras theorem,
D² = (40t)² + (60t)²
D² = 1600t² + 3600t²
D² = 5200t²
D = √(5200t²)
