Anyone good with rate, time and distance word problems? I only got two problems left and if someone would just help me set them up I'm sure I can finsh them.. pls pls pls

1.) Two cyclists, 42 miles apart, start riding toward each other at the same time. One cycles 2 times as fast as the other. If they meet 2 hours later, what is the speed (in mi/h) of the faster cyclist?

2.)Mutt and Jeff need to paint a fence. Mutt can do the job alone 5 hours faster than Jeff. If together they work for 24 hours and finish only of the job, how long would Jeff need to do the job alone?

anonymous · Answer

first one we can say that their combined speed is 3x and then solve 
$$42=6x$$ for x

anonymous · Answer

x=7

anonymous · Answer

i.e. distance = rate times time, distance = 42, rate is 3x and time is 2 hours.  so one has rate 7 and the other has rate 21

are you missing part of the second one?

anonymous · Answer

second one the copy and paste didn't work because of the image

anonymous · Answer

yeah in 24 hours they only finish  7/8 of the job
