Martha leaves home at AM bicycling at a rate of 24 miles per hour.?

Question

Two hours later, JOhn leaves driving at the rate of 48 miles per hour. At what time will JOhn catch up with Martina?

Answer 1

You didn't say what time Martha left. It will take John 2 hours to catch up with Martha, which will be 4 hours from the time MARTHA left the house (assuming they left from the same house). So if Martha left the house at, say, 8 a.m., John will catch up with her at noon.

End of hour 1: Martha 24, John 0
End of hour 2: Martha 48, John 0
End of hour 3 for Martha, hour 1 for John: Martha 72, John 48
End of hour 4 for Martha, hour 2 for John: Martha 96, John 96

Answer 2

Martha has a 2 hour head start up wherein era she rides 24 x 2 = forty 8 miles. verify how many miles in line with hour swifter John can force, and divide forty 8 with the help of this to verify how many hours it takes him to capture up.

Answer 3

two and a half hours later

Answer 4

x=v*t+x(0)

you know velocity for each, set x equal to one another, solve for time. you have to first figure out x(0).

Answer 5

I always had and still do have problems with word problems. Can't help you there.
