- Tim’s trip
It’s 7km from Tim’s house to where his Grandma lives.
It’s uphill on the way there so he can only cycle at 14 kph
but he can do 21 kph on the way back.
Tim leaves his house at 6pm.
How long can he stop at his Grandma’s house if
he wants to be back home for his favourite
TV programme at 7pm?
So Tim has an hour to travel back and forth to
his grandma’s house with in an hour as well as his
spending time with nana.
30 mins on his way their = 14kph
20 mins on his way back = 21 kph
10 mins with Nana
It took Tim longer to get to his Nena’s house because
he was travelling uphill on a slower speed.
good job nice=
