Question

Dale and Betty go through a traffic light at the same time but Dale goes straight and Betty turns right. After two minutes Dale is 2000 yd from the intersection and Bettyis 750 yd from the intersection. Assuming the roads met at a right angle and both were perfectly straight, how far are Dale and Betty away from each other after two minutes?

Answer 1

2,136 yards

Explanation:

Since the roads met at a right angle, the distance between Dale and Betty can be interpreted as the hypotenuse of a right triangle with sides measuring 2000 yd and 750 yd. The distance between them is:

`d^2=2000^2+750^2\\d=√(2000^2+750^2)\\d=2,136\ yards`

Dale and Betty are 2,136 yards away from each other after two minutes.
