johnny leaves his home to visit his cousin, anne, who lives 74 miles away.

Question

he travels at an average speed of 46 miles per hour. one half hour later, anne leaves her house to visit johnny, traveling at an average speed of 56 miles per hour. how long after anne leaves will the two meet?

Answer 1

d = r · t

 

d_johnny = 46(t + 0.5)

d_anne = 56t

 

d_johnny + d_anne = 74

46(t + 0.5) + 56t = 74

 

Can you solve for t?
