An old man driving bike at 80 km per hour. However being sugar patient, old man could not travel continuously. He takes small breaks each of 2 minutes for every 15 minute of his drive. How much distance the old man will cover in 90 minutes?

An old man driving bike at 80 km per hour. However being sugar patient, old man could not travel continuously. He takes small breaks each of 2 minutes for every 15 minute of his drive. How much distance the old man will cover in 90 minutes? Correct Answer 104 Km

For every 15 minutes he takes a rest of 2 minutes.Hence, for 90 minutes of drive he would require 12 minutes of rest. Thus, he will be traveling for 90 - 12 = 78 minutes.In 60 minutes he covers 80 Km.In 1 minute he would cover $$\frac{{80}}{{60}}$$ Km.In 78 minutes he would cover $$\frac{{80}}{{60}} \times 78$$   = 104 Km.

Study the two cases and answer in terms of relation between the two cases Case 1: The average speed of the bike is \(3\frac{3}{4}\) times the average speed of the bus. A car covers 720 km in 10 hours. How much distance (in km) will a bike cover in 50 minutes if the speed of the bus is half of the speed of the car? Case 2: The average speed of bike is \(1\frac{2}{5}\) times the average speed of the car. A bus covers 441 km in 7 hours. How much distance (in km) will a bike cover in 45 minutes if the speed of the car is twice the speed of the bus?

Arun drove from home to his hostel at 60 miles per hour. While returning home he drove half way along the same route at a speed of 25 miles per hour and then took a bypass road which increased his driving distance by 5 miles, but allowed him to drive at 50 miles per hour along this bypass road. If his return journey took 30 minutes more than his onward journey, then the total distance traveled by him is
Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers. Quantity A: A person who travels a certain distance to his office by his car.If he increases his speed by 8 km/hr, he takes 2 hours less time but if he drives 8 km/hr slower, he takes 4 hours more time. Find the distance of office from home. Quantity B: A person who travels a certain distance to his office by his car. If he increases his speed by 10 km/hr, he takes 1 hour less time but if he further increases his speed by 5 km/hr, he takes further 20 minutes lesser time. Find the distance of office from home.
when a truck travels at 60 miles per hour, it uses 30 percent more gasoline to travel andy distance than it does when it travels at 50 miles per hour. The truck can travel 20 miles on a gallon of gas if it is travelling at 50 miles per hour. The truck has only 10 gallons of gas and is 160 miles from its destination. It takes 20 minutes for the truck to stop for gas . How long will it take the truck to reach its final destination if it is driven at 60 miles per hour?
Three bikes leave A for B in equal time intervals. They reach B simultaneously and then leave for Point C which is 240 km away from B. The first bike arrives at C an hour after the second bike. The third bike, having reached C, immediately turns back and heads towards B. The first and the third bike meet a point that is 80 km away from C. What is the difference between the speed of the first and the third bike?
