Question

Sasha can run at an average speed of 9 3/4 min/mi. She runs at this speed for 68 1/4 min.

How many miles does Sasha run?

Answer 1

9 3/4 = 36/4 mi/m

68 1/4 = 17/4 min

36/4 mutiply by 17/4 = 10647 / 16 mi = 2 8/68mi

Answer 2

9 3/4 = 39/4 mi/m

68 1/4 = 273/4 min

39/4 mutiply by 273/4 = 10647 / 16 mi = 665.4 mi
