Lesson: Uniform Speed Mathematics
In this lesson, we will learn how to solve problems about motion of a body with constant speed using the definition of speed, speed = distance/time.
Two cars traveled from city to city along a route which is 54 km long. They both departed city at the same time. If the speed of the first car was 40 km/h and the speed of the second car was 60 km/h, what is the time difference between their arrival times at city ? Give your answer in minutes.
Two cars were moving in opposite directions on a road between and . The first car started at point and traveled at 104 km/h, and the second started at point and traveled at 100 km/h. Given that the points and are 153 km apart, determine the time and the distance from point at which the two cars met.
A train traveling with a uniform speed of 180 km/h passed through a tunnel in 18 seconds. Given that the train was 210 meters long, find the length of the tunnel.
