A group of students investigated the effect of temperature of vinegar on its reaction time with baking soda. To minimize the ran
dom errors, they did 3 trials for each temperature change. The following data were collected. At 30 °C, the times it takes for baking soda to react in seconds are 30.1, 30.9 and 30.2 for Trials 1, 2 and 3 respectively. At 55 °C, they recorded the reaction times for the three trials as 25.6 s, 25.9 s and 25.5 s. At 60 °C, the data were 20.0 s, 19.8 s and 19.3s for the three trials. At 75 °C, they recorded the reaction times for the three trials as 15.0 s, 15.2 s and 15.5s. At 90 °C, the reaction times gathered for the three trials are 8.3 s, 8.9 s and 8.8 s.

next time you answer someone's question with a bunch of random letters just to get the points don't. It rude especially sense you have questions you want answered. Now I could be nice and help you because I know how to solve this and you obviously don't, but I'm giving you the same curtesy as you did me and writing a bunch of gibberish.
Step-by-step explanation: We see that it took James 10 minutes to go 0.5 miles, so to get how many miles an hour James is traveling, we need to get the miles to 1. To do this, multiply by 2, and this will give you that it took James 20 minutes to go 1 mile. This is option C.
Because it goes up by five for they gave us the amount of point they get for 5 hours and the amount of point he had for 5 hours was 50 so we just needed to add 5 more and 50+5= 55
I don't know if I made myself clear but good luck! :)
