In this lesson, we will learn how to solve rate problems using the formula d = rt, where d represents distance, r represents rate, and t represents time.

Q1:

A train travelling 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.

Q2:

A motorcycle started moving from a point π΄ at a uniform speed. Given that, after 3 minutes, it was 2 km from π΄ , and, after 8 minutes, it was 18 km from the same point, determine the speed of the motorcycle.

Q3:

If a body covered meters in 10 minutes with a uniform velocity of 44 m/min, find the time taken to cover this distance when the body moves with a velocity of 20 m/min.
