She dives 60 mi in clear weather and then encounters a thunderstorm for the last 17 mi. She drives 23 mph slower through the thunderstorm than she does in clear weather. If the total time for the trip is 2.5 hr determine her speed driving in nice weather and her speed driving in the thunderstorm. Part 1 out of 2 Barbara drives mph in nice weather

Explanation / Answer

let her speed in clear wheather be x

her speed in thunder strom is (x-23)

speed=distance /time

time in nice wheather=60/x

time in thunder strom =17/(x-23)

given total time=2.5hr

60/x +17/(x-23) =2.5

60(x-23)+17x=2.5(x)*(x-23)

x=40,69/5

x can not be 69/5 =13.8 since (x-23 ) is negative

so speed in nice wheather =40mph
