Question

A boat sailed 560 km in 8 hours. It took three hours to travel

the first 150 km. What was its average speed for the
remaining journey?
km/h​

Answer 1

Explanation:

150 km in 3 hours

= 150 ÷ 3 = 50km/h

Remaining distance = 560 - 150 = 410

Remaining hours = 8 - 3 = 5

Then average speed = 410 ÷ 5 = 82 km / h
