Question

The bell has rung and Caden is walking to his next class. He walks 150m in 1 minute and

then students block his way and he has to stop for 1 minute. He then walks 500m in 1
minute. What was his average speed?

Answer 1

`3(11)/(18)` m/s

Explanation:

Caden walks 150m in 1 minute

A student blocks his way and he has to stop for 1 minute

He then walks 500m in 1 minute.

1 minute = 60 seconds

Let's use 's' to stand for seconds and 'm' to stand for meters.

Average speed = Total distance ÷ total time taken.

Total distance = 150m + 500m = 650m

Total time taken = 60s + 60s + 60s = 180s

Average speed = 650m ÷ 180s =
`(650)/(180) = 3(11)/(18)` m/s
