Meg jogs at a rate of 10km/h faster that Kier walks. If Kier walks at 4 km/h and leaves at 9:00 and Meg leaves 1/2 hr later, at what time will they be 5 km apart?
Thank you for the opportunity to help you with your question!
here, you note the following
meg jogs at at 10 km.h + 4 km/h. a total of 14hm/h...
here are the calculations
14 - 4 (km.h) because they are moving in the same direction: = 10
then, at 10 km/h difference, the difference of 5 KM, should be in 30 minutes time.
but Meg was late by 30 minutes and kier had moved for 2 km
so, they met at 9: 40
for 5 kilometers difference it would be at
10:10, which is 9:40 Plus 30 mins
