Problema Solution
Derek's car travels 15mph faster than Shawn's car. In the same time that Derek's car travels 295 miles, Shawn travels 220 miles. Find the speed of each of their cars
Answer provided by our tutors
295 = (v +15)* t
220 = v*t
dividing
295/220 = v+15/v
295v = 220v +3300
75v = 3300
v = 44
and 44+15 = 59
so velocities are 44 mph and 59 mph
