6th Grade Word Problems (Average Speed)

The following are some examples of 6th Grade Math Word Problems that deals with average speeds.

Example:

Point A and Point B are 120 m apart. Point B and Point C are 300 m apart. Ben ran from Point A to Point B in 15 seconds. Then, he runs from Point B to Point C in 55 seconds. Find Ben’s average speed for the distance from Point A to Point C.

Solution:

Total distance from Point A to Point C = 120 + 300 = 420 m

Time taken to run from Point A to Point C = 15 + 55 = 70 s

Ben’s average speed is 6 m/s.

Example:

Pauline swam for 100 seconds at a speed of 2.5 m/s. Then, she swam for another 100 seconds at a speed of 1.5 m/s. Find Pauline’s average speed.

Solution:

For the first part,

Distance swum = 2.5 × 100 = 250 m

For the second part,

Distance swum = 1.5 × 100 = 150 m

Total distance swum = 250 + 150 = 400 m

Total time taken = 100 + 100 = 200 s

Average speed = 400 ÷ 200 = 2 m/s

Pauline’s average speed was 2 m/s
