Question

Jon leaves his house at 45 miles per hour. a half hour later, his wife Emily leaves at 55 miles per hour. how long does it take to meet

Answer 1

Hi There,

 

Let's begin by knowing that at the time Emily catches up with Jon - they would each have traveled the same distance.  Therefore, we can write this equation to solve for that time (t):

    Emily's distance = Jon's distance

    55t = 45(t + 0.5)

    55t = 45t + 22.5

    55t - 45t = 22.5

    10t = 22.5

    t = 22.5/10

    t = 2.25 hours

 

Thanks for submitting this problem and glad to help.

 

God bless, Jordan.
