Question

jennifer drove her car for 3 hours in a dust storm. When the skies cleared, she increased her speed by 30 miles per hour and drove for 4 more hours, completing her 295 mile trip. How fast did she travel during the dust storm?

Answer 1

Distance made at the last 4hours=4*30=120miles

Distance made at the dust storm=295-120=175miles

Dust storm speed =175/3=58.333333 miles per hoyr

Answer 2

25 mph.

Let v = speed during dust storm

3v + 4(v+30) = 295

7v + 120 = 295

7v = 175

v = 25

Answer 3

Figure it out yourself, you don't need people to do your homework for you.
