Question

Taylor ran 57 minutes on Tuesday and 48 minutes on Saturday. Mark ran 62 minutes on Tuesday and 53 minutes on Saturday. Taylor said they ran the same total time and mark said they didn’t. Who is right? Explain using comparative relational thinking.

Answer 1

Let's compare!

Taylor ran 57 + 48 mins total. Sum would be 105 mins.

Mark ran 62 + 53 mins total. Sum would be 115 mins.

Clearly, the two sums are different when we compare them using subtraction.

115 - 105 = 10. Mark ran 10 mins longer than Taylor.

Answer 2

No they didn’t. So that makes mark right, because I’m an hour there is 60mins so Taylor’s time—57+48=105-60=45 that would be 1.45 (1hr45mins) Marks time— 62+53=115-60=55 so that would be 1.55(1hr55mins)
