Question

At 3:00 ok a truck and a car leave the same intersection traveling in the same direction. The truck is traveling at 43 mph and the car is traveling at 58 mph. At what time will they be 12 mi apart?

Answer 1

58t-43t = 12

15t=12

t=12/15 = 0.8 hours

0.8*60= 48 minutes

3:00 + 48 minutes = 3:48
