Step-by-step explanation:
The speed of the first runner is 1.78 mph while for the second runner is 2.22 mph
<h3>
Speed</h3>
Speed is the ratio of total distance to total time taken. It is given by:
Speed = distance / time
Let a represent the speed of the first runner and b for the second runner. Hence:
a = (4/5)b
After 30 minutes (0.5 hour), the runners are 2 miles apart, hence:
a = d₁ / 0.5
d₁ = 0.5a
Also:
b = d₂/0.5
d₂ = 0.5b
d₁ + d₂ = 2, hence:
0.5a + 0.5b = 2
0.5(4/5)b + 0.5b = 2
b = 2.22 mph
a = (4/5) * 2.22 = 1.78 mph
The speed of the first runner is 1.78 mph while for the second runner is 2.22 mph
