Question 754334: Jane has to drive 60 miles to her parents. How long will the journey take if she drives at:
a) 40 mph
b) 50 mph
c) 60 mph?
Answer by anteater(7)   (Show Source):
You can put this solution on YOUR website! Since distance = rate X time, we can plug the given information into that formula and solve for the missing amount.
a) d = rt --> 60 miles = (40 miles/h)X t --> 60 miles/40 mph = t -->
6/4 hours = t
So, when she is driving at 40 mph, it will take her 6/4 hours or 1 1/2 hours or 90 minutes to drive 60 miles.
b) d = rt --> 60 miles = (50 miles/h) X t --> 60 miles/50 mph = t -->
6/5 hours = t
So, when she is driving at 50 mph, it will take her 6/5 hours or 1 1/5 hours or 72 minutes to drive 60 miles.
c. d = rt --> 60 miles = (60 miles/h) X t --> 60 miles/60 mph = t -->
1 hour = t
So, when she is driving at 60 mph, it will take her 1 hour or 60 minutes to drive 60 miles.
