Question

A cyclist travels 2/3 of his journey at the average speed of 12 miles per hour. He then travels the remaining 30 miles of his journey in 3 hours. How long does his trip take?

Answer 1

Distance=Velocity x TiME
T=s/v
T=60/12
T=50 hrs
TOTAL TIME OF JOURNEY =5+3=8HRS

Answer 2

The cyclist or bikers were able to travel 2/3 of his journey at the average speed of 12 miles/hour.Then the remaining 1/3 of his journey which is 30 miles for 3 hours.Let's find out how many miles did he travelled and what is the average unit rate of his travel.=> Since 1/3 of his trip is 30 miles, thus 2/3 of his trip is 60 miles.=> 30 + 60 = 90 miles is his total trip
12 miles per hour for his 60 miles.=> 60 miles / 12 miles per hour = 5 hours.60 miles for 5 hours.30 miles for 3 hours => 90 miles for 8 hours.=> 90 / 8 = 11.25 miles per hour.
