Question

To get to michael's house, angela leaves her house travelling at 40km/h along a road in an easterly direction for 45min. she then takes a 30 deg right turn onto a second road and travels at 50km/h for 30min before arriving at michaels house. determine an exact expression for the distance between the two houses.

Answer 1

45/60*40+1/2*50

Answer 2

How do we get that?

Answer 3

first she travels 45mins out of 60 mins of the 40km/h
then, she travels for another 30mins out of 60 mins of the 50km/h (I simplified the fraction to make it 1/2)

Answer 4

Then I added them together to get the total distance. Does that make sense? :/

Answer 5

oh i get it!
