Question

Julia and Anthony each ride their bicycles along a path to the park. The equations that represent their distances in miles from the park as a function of time in minutes are:

Julia: d = 0.25t

Anthony: d = 4.5 – 0.20t



What is their distance from the park when they meet on their bicycles?

Answer 1

2.5 miles just took the test

Answer 2

Their distance from the park when they meet on their bicycles = 2.5 miles

Explanation:

The equations that represent their distances in miles from the park as a function of time in minutes are:

Julia: d = 0.25t and Anthony: d = 4.5 – 0.20t

We need to find their distance from the park when they meet on their bicycles.

When they meet their distance is same that is

d = 0.25t = 4.5 – 0.20t

0.45 t = 4.5

t = 10 minutes

Distance from park when t = 10 s

d = 0.25 x 10 = 2.5 miles

Their distance from the park when they meet on their bicycles = 2.5 miles
