A jet left Tokyo and Lea towards Moscow. An airdrome jet left one hour later flying 35kph faster in order to catch up tobit. After ten hours the air force jet caught up. Find the jets average speed.
The answer is 350. Since it is 35 kilometers per hour, first you have 35kph since the jet left one hour ago. Then it say after 10 hours, so you multiply 35×10=350 kilometers
