The distance between cars moving along the highway is 100 km. Vehicle speeds are 75 km / h and 90 km / h.

The distance between cars moving along the highway is 100 km. Vehicle speeds are 75 km / h and 90 km / h. What is the smallest distance between them can be in 1 hour and 12 minutes? In the answer, write down only the number without units of measurement.

If the cars are moving in different directions, which is more likely, then their removal speed must be calculated. To do this, add 75 and 90:
1) 75 + 90 = 165 km / h
Next, you need to calculate how much the distance will increase. To do this, we need to multiply 165 km / h by the time:
2) 165 * 1.12 = 184.8 km
Now we add the initial 100 km:
3) 184.8 km + 100 km = 284.8 km
Answer: 284.8
