Lauren and Aidan left their offices at 6:15 p. m. and drove to meet at a restaurant the same distance away from their offices for dinner. Lauren drove at a constant speed of 39 miles per hour.
Aidan drove at a constant speed of 42 miles per hour.
Aidan reached the restaurant at 6:35 p. m.
How far away was Lauren from the restaurant when Aidan reached?

distance=speed(time)

Let, t be the time it took for Karen to catch up with Renee;

Karen: d= 28t

Renee: d= 20(2 +t). Renee has already travelled for two hours.

The distance they travelled will be equal, when Karen catches up with Renee, so set the equations equal to each othe,

28t = 20(2 + t)

28t = 40 + 20t

8t = 40

 t = 5

The answer is after 5 hours.

Step-by-step explanation:

only 10/60 isn't equivalent

hope this : )

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
