# Worksheet: Uniform Speed

In this worksheet, we will practice solving problems about motion of a body with constant speed using the definition of speed, speed = distance/time.

Q1:

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.

Q2:

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,
• B,
• C,
• D,
• E,

Q3:

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.

Q4:

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

Q5:

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.

Q6:

Liam starts walking along a path at a constant 4 mph. One and a half hours after Liam leaves, his sister Scarlett starts jogging along the same route at a constant 6 mph. How long will it take Scarlett to catch up with Liam?

Q7:

A man was walking on a railroad bridge , which starts at point . He heard the whistle of a train coming from beyond point after he had covered of the bridge’s length. The train was heading toward him at a uniform speed of 20 km/h. Given that, at a certain speed, the man could either run toward and narrowly avoid the train there or run toward and narrowly avoid the train there, what is the minimum uniform speed that he must move with in order to avoid being hit by the train?

Q8:

Two bodies started moving from points and in the direction of , where the distance between them was 35 km. Given that the bodies were moving with uniform velocities of 1,400 m/min and 119 km/h, respectively, and that they met at a distance from after minutes, find and .

• A,
• B,
• C,
• D,
• E,

Q9:

If a car moved with uniform speed 36 km/h for of an hour, then the distance covered is km.

• A12
• B18
• C24
• D108

Q10:

A body moved with a uniform speed of 100 km/h for 2 hours. What is the distance covered by the body in meters?

Q11:

A car travels a distance of 180 km in 2 h. What is the uniform speed of the car in meters per second?

Q12:

If a car moves with uniform speed 60 km/h for 20 minutes, then the distance covered .

• A20
• B120
• C60
• D80
