How far apart are the two ships after 3 hours?

Question

Two ships head in opposite directions, one is traveling at 12 kilometers per hour and the other is traveling at 16 kilometers per hour. How far apart are the two ships after 3 hours?

Answer 1

Assuming they start at the same place...

Ship A distance = 12 km/hr x 3 hrs = 36 km

Ship B distance = 16 km/hr x 3 hrs = 48 km

Distance separating ship A and ship B = 36 km + 48 km = 84 km
