Answer:
5 miles towards north
Step-by-step explanation:
Given that:
Desiree drove towards north.
Time for which Desiree drove north = 30 minutes
Speed while driving north = 50 miles per hour.
Then Desiree drove towards south.
Time for which Desiree drove south = 60 minutes
Speed while driving south = 20 miles per hour.
To find:
The distance and the direction in which Desiree is now from where she has started?
Solution:
Formula for distance traveled can be given as:
Let us convert the given time in hours first.
While traveling north, time = 30 minutes = hours
Distance traveled towards north = 50
= 25 miles
Then she started traveling south i.e. in the direction just opposite to earlier direction.
While traveling south, time = 60 minutes = 1 hour
Distance traveled towards south = 20 1 = 20 miles
So, the distance at which she is from the starting point = 25 miles towards north - 20 miles towards south = <em>5 miles towards north </em>
