Answer:
1.5 hours
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Aya and Mary distance = 12 miles
Let, meeting point from Aya = Z miles
So, Aya covers Z miles to reach Mary.
Hence, Mary covers (12 - Z ) miles to reach Aya
Here, Time =
Aya =
Mary =
If, same time taken, then we can solve by following method,
By solving the equation, we get
Z = 60 ÷ 8
Or Z = 7.5 miles
Hence, time taken for both to meet = 7.5 ÷ 5
= 1.5 hours
