53 piles for 1 hour #-> # 53 miles per hour

Making the unit rate based on time# ->time=1#
#("Distance traveled")/("Time traveled in hours")->424/8#
#color(brown)("So we need to change the eight to one.")#

What we do to the bottom we do to the top to maintain the ratio. That is, for multiply or divide. Add or subtract 'messes that up' and needs special treatment.

#("Distance traveled")/("Time traveled")->424/8->(424-:8)/(8-:8) = 53/1#
#color(green)("So for 1 hour (unit rate) the distance traveled is 53 miles")#

Answer 3

To write the ratio 424 kilometers in 8 hours as a unit rate, you divide the total distance by the total time.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
