last weeekend trisha and becca both went on a bike ride trisha biked 8 miles in two hours and becca biked 10 kilometers in 7800
S_A_V [24]
So first I’m going to change the 10 kilometre in miles which is 6.214 miles
Then I’m going to convert 7800 seconds in hours which is 2.16 hours so now the data shows that Trisha biked 8 miles in 2 hours and becca biked 6.214 miles in 2.16 hours
So Trisha was faster than becca
