Practice Problems. Question 1: A car travels 60 km in 30 minutes. What is the speed of the car? Solution: Distance covered by the car = 60 km. Time taken to cover the distance = 30 min. Speed of the car = Distance ÷ Time = 60 km ÷ 30 min = 2 km/min. Answer : 2 km/min. Question 2: Arun ran a marathon of 2 km in 10 minutes. What is his speed?
This document provides formulas and examples related to time, speed, and distance. It includes 8 formulas covering topics like: 1) The relationship between distance, speed, and time 2) Average speed when a journey is divided into different parts 3) Relative speed when objects are moving in the same or opposite directions 4) Calculating stoppage ...
Example 1. A train leaves a station at 9:00 AM and travels with a constant speed of 90 km/h. Another train leaves the same station 10 minutes later, traveling to the same direction at the speed of 100 km/h. At what time will the second train reach the first? We will be using the formula d = vt extensively in these problems. Let’s build a chart.
18.2 Calculating Speed, Distance and Time In this section we extend the ideas of speed to calculating distances and times, using the following formulae: Speed = Distance Time Distance =Speed Time× Time = Distance Speed Example 1 Jane drives at an average speed of 45 mph on a journey of 135 miles. How long does the journey take? Solution Time ...
A. Speed = Distance/Time. B. Time = Distance/Speed. C. Distance = Speed × Time In some questions you will be given speed in kilometres per hour (km/hr) and you will have to convert it in meters per second (m/s) and vice versa. We know that 1 km equals 1000 meters and 1 hour is 3600 seconds.
Speed is the distance you are travelling, divided by the length of time that it takes you to get there. Speed =. Similarly, we can rearrange this equation as. Distance = Speed x Time. and. Time =. Example. This chart describes the distance between four towns. Distance (miles)
average speed = distance moved ÷ time taken. acceleration = change in velocity ÷ time taken . plot and explain distance-time and velocity-time graphs . determine: acceleration from the gradient of a velocity-time graph. distance travelled from velocity-time graph. use the relationship v2 = u2 + 2as.
