Best ResponseYou've already chosen the best response.0It took Jimena 89 minutes to run a 15kilometer race last weekend. If you know that 1 kilometer equals 0.621 mile, how many minutes did it take Jimena to run 1 mile during the race? Round your answer to the nearest hundredth. 3.68 minutes 9.55 minutes 9.88 minutes 24.15 minutes

Best ResponseYou've already chosen the best response.3First, you would need to know how many minutes it took her to run 1 kilometer. This would be set up in a proportion: \[\frac{ 15 }{ 89 } = \frac{ 1 }{ x }\] Solve for x to find how many kilometers she ran in 1 minute. Then transfer it to minutes per mile. Do you know how to do that?

Best ResponseYou've already chosen the best response.0okay so jimena's rate is 15 km/ 89 minutes convert this to 0.16853932584 km/ min which is equal to 0.16853932584(.621) miles/min set that [rate] equal to d/t so 0.16853932584(.621)=d [1 mile]/t solve for t

Best ResponseYou've already chosen the best response.3To solve proportions, you crossmultiply by multiplying the terms that are diagonal to each other.

Best ResponseYou've already chosen the best response.0She takes 89 min to cover (15×0.62)miles So for 9 miles time is 89min. For 1mile time taken is 89/9minutes =9.88min. (Approximately)

Best ResponseYou've already chosen the best response.3Yep, now multiply it by the conversion of km to miles to find the answer (Hint: Multiply it by 0.621)

Best ResponseYou've already chosen the best response.3Hold on, I screwed up. You have to convert the 15 km into miles using the conversion given.

Best ResponseYou've already chosen the best response.3Once you find how many miles is in 15km, you set up the same proportion we did earlier, except swap the 15 with the new value that you get
