All the times, she walked in the same route. When she walks faster the time she takes to reach her home and school is lower. There is nothing wrong with the statement. They never mentioned how long she took every time.
Let the speed be x. Equate these two and get the answer. Now, you have 3 equations with 3 unknowns. The variables x and y represent the usual speed and usual time to travel distance d.

Tags gmat quantitative. Problems involving Time, Distance and Speed are solved based on one simple formula.
Let us see how this question can be solved. Solution For these kinds of questions, a table like this might make it easier to solve.
Solution Here, we see that the distance is same. So the actual time taken to cover the distance is 15 minutes. Solved Questions on Trains Example 1. So the slower train is moving at the rate of 40 mph. More solved examples on Speed, Distance and Time Example 1. Substituting the value of t in 40 3-t , we get the distance travelled by bus is 40 miles.
Alternatively, we can add the time and equate it to 3 hours, which directly gives the distance. Solution Our table looks like this. Practice Questions for you to solve Problem 1. A 30 kmph B 20 kmph C 15 kmph D 40kmph.
Answer 1. Problem 2. A 30 miles B 35 miles C 40 miles D miles. Answer 2. Hire us to improve your chances of getting into the top international universities. Email: info [at] mbacrystalball [dot] com.

Sol In this problem we cannot directly use the formula first we need to find the upstream speed and speed in still water. This can be done as follows,. Example 5: A person challenged himself to cross a small river and back. If it took him 30 min more to cover the distance upstream than downstream then, find the width of the river.
If a boat takes t hours to row to a place and return back, then the distance between the two places can be estimated through. If in a river running at 1. Sol To solve this question we will simply use the formula given above. In this case, t is 50 minutes b is 1.
