Starting at the same point, Tom and Juanita go biking in opposite directions. If Tom rides at a speed of 18 mph, and Juanita rides at a speed of 20 mph, how far apart will they be in 2 hours?

Answer 1

Since Tom and Juanita are biking in opposite directions, their distances from the starting point will be increasing at a combined rate of 18 mph + 20 mph = 38 mph.

In 2 hours, their combined distance from the starting point will be:

distance = rate x time
distance = 38 mph x 2 hours
distance = 76 miles

Therefore, Tom and Juanita will be 76 miles apart after 2 hours of biking in opposite directions.
