Question

A car travels at an average speed of
68
miles per hour. How long does it take to travel
306
miles?

Answer 1

use the formula \[\Large D = r*t\]

Answer 2

D = distance, which in this case is 306 miles
r = rate (aka speed) which is 68 mph
t = unknown but you use the formula above to solve for t

Answer 3

D = r*t

306 = 68*t .... plug in the known values

solve for t

Answer 4

4.5

Answer 5

yep so it will take 4.5 hours (4.5 hrs = 4 hrs, 30 minutes)
