Answer: Danielle drive for 2 hours
Jamal drives for 2 × 3 = 6 hours
Step-by-step explanation:
Let the number of hours that Danielle used in driving to be represented by x.
Since Jamal drives 3 times the hours that Danielle does. This will be:
= 3 × x = 3x
Since Jamal and Danielle drive for a total of 8 hours. This can be formed into a equation as:
x + 3x = 8
4x = 8
x = 8/4
x = 2
Danielle drive for 2 hours
Jamal drives for 2 × 3 = 6 hours
The right answer is 10√5..
