To calculate: Time atAndrew and Stacey meet each other.
Answer to Problem 7P
11:30 am.
Explanation of Solution
Given information:
At 9:30 A.M. Andrew left Exeter for Portsmouth cycling at 12min/hr.
At 10 A.M. Stacey left Portsmouth for Exeter cycling at 16min/hr.
The distance from Exeter to Portsmouth is 20 miles.
Formula used:
Calculation:
According to question,
Let, t= Stacey’s travel time
The distance equation is given by,
Stacey distance =
Andrew’s distance =
When Stacey overtakes Andrew, they have travelled the same distance,
Therefore,
Stacey’s travel time started at 10:00A.M,
Thus,
Confirmingit by finding the actual distance each travelled,
Since both of them travelled same distance the equation formed is correct.
So, they met at 11:30 A.M.
