I ran for 1hr 15mins on the threadmill at an average speed of 8.1km/h.
Let me recall my maths... distance= speed x time
This should be about 10km then.
Primary school maths isn't so straight forward anymore!!!
My friend posted this in her FB-- a Primary 4 Maths question:
MRT is 2/5 full. 1/2 got out and 17 came in and it was 1/4 full. How many people were there at first?
Try solving it without algebra!!!!

136?
Primary 4 can use fraction, right？
1/2 of 2/5 = 1/5 = 4/20
1/4 = 5/20 = 4/20 + 1/20
so, 1/20 = 17,
As 2/5 = 8/20,
Original number will be 8x17, ie 136?
yp :)

Hi Angie,

Wah. I'm so not gonna make it if I teach Faith math!! My answer worked out to be 136 but that's only when I used percentage. I don't understand the fraction method!
Look like I also hv to look for tution teacher for my gal in 5 yrs time... :-(
It depends which line you are taking. EW, NS train got driver.
NEL and circle no driver.
In the first place, when do you see MRT 2/5 full???
Poor context and not realistic at all! Lousy question!
