Aboat heads north at 30 mph while a steamer heads east at 40 mph at the same time. when is the distance between them 50 mi? a boat heads north at 30 mph while a steamer heads east at 40 mph at the same time. when is the distance between them 50 mi?

1 hour

Explanation:

Speed of the first boat = 30 mph

Speed of the second = 40 mph

The boats will cover different distances but the time taken will be the same.

Time taken by the boats = t

Distance = Speed × Time

Distance covered by the first boat = 30t

Distance covered by the second boat = 40t

Distance between the boats = 50 mi

From the Pythagoras theorem

Time taken by the boats when they are 50 mi away is 1 hour
