Answer 1

Answer:

The car should travel at 65km/hr for 2 hours

Step-by-step explanation:

The car has already traveled 150km (50km * 3 hours)

So we need to subtract that from the initial distance (280 - 150) to get 130km

Then we need to take the time needed to travel and subtract that by the time that  has already been traveled (5 - 3) to get 2 hours

Divide 2 from 130 (130/2) to get 65km
