Answer to Problem 20CT
Jessie swam at the rate of 3.4 km/h and Lee swam at the rate of 4.4 km/h
Explanation of Solution
Given information: Lee and Jessie swam towards each other from opposite sides is a lake that is 3.9 km wide.
Calculation: First we calculate the distance traveled by Jessie
Let speed of Jessie is
As speed of Jessie is
As given sum of distances traveled by both is 3.9 km, so
So, Speed of Jessie is 3.4 km/h and speed of Lee is 3.4+1=4.4 km/h
Conclusion: Jessie swam at the rate of 3.4 km/h and Lee swam at the rate of 4.4 km/h.
