A sailboat is sailing at 8 1/2 km/h. If the weather conditions and the current do not change, how far will the sailboat travel in 1 1/3 h?
8 1/2 x 11/3= 68/6 =11 1/3
The sailboat will travel 11 1/3 km2 2/5 x 7/1 = 12/5 x 7/1 =84/5 =16 4/5

#4
The distance to Grandma's house is 4/5 of the distance to Uncle Glen's house. If Uncle Glen's house is 3 1/2 hours away, how long will it take to get to Grandma's house if you travel at the same speed?
3 1/2 x 4/5 = 28/10 =2 8/10 =2 4/5
it would take 2 4/5 of an hour to get to grandma's house.
3 1/2 x 4/5 = 28/10 =2 8/10 =2 4/5
it would take 2 4/5 of an hour to get to grandma's house.

2 1/4 x 8/1= 2/1 x 8/1= 18/1 =18
2 1/4 x 8/1= 2/1 x 8/1= 18/1 =18
When Robin is 8 Owen will be 18 years old.
