The time taken for Jada's and Destiny's travel are 0.5595hour and 0.3928 hour
Let us consider distance for which both had to travel be equal
Let this time be 't'
The total distance between them is 65 miles
It is given that speed of Jada and Destiny are 60 and 80 mph
It is also given Destiny starts the journey 10 minutes later, hence her time be t-10 mins
But as all units are in hour , we must convert 10 mins to hour,
10 mins = 0.1667 hours
there Destiny's time of travel = t - 0.1667
We know that distance = speed x time
Therefore, total distance = distance travelled by Jada+ Distance travelled by Destiny
65 = 60 x t + 80 x(t-0.1667)
65 = 60t + 80t - 13.336
78.336 = 140 t
t = 78.336/140 = 0.5595hr
t= 0.5595 hour
Time taken for Jada's travel = 0.5595 hours
Time taken for Destiny's travel = t-0.1667 =0.5595-0.1667 =0.3928 hour
