Tiana takes 3 hours to drive to the coast without stopping how many minutes will it take her to reach the coast if she stops to rest for 20 minutes

Tiana takes 3 hours to drive without stopping. We know tha one hour is equivalent to 60 minutes, and then 3 hours are 3 x 60 minutes = 180 minutes. This means she reached the coast without stopping in 180minutes. If we assumed she stopped to rest for 20 minutes, so the remaining time is 180 minutes - 20 minutes = 160minutesHope this helps. Let me know if you need additional help!

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
