Question

Jessica jogged 623 meters in 4 minutes, 22 seconds. What is her speed?

Group of answer choices

1.6 m/s

0.42 m/s

2.4 m/s

0.86 m/s

Answer 1

V=Distance/time
S=623m
T=4 minutes = 4*60sec= 240 seconds
V=S/T=623m/240sec
V=2.5m/sec……2.4m/sec

Answer 2

2.4 m/s

Step-by-step explanation:

The formula for speed is s = d/t

We have the distance and time so plug those numbers in

623/4.22 We can't divide the number like this so...

Convert the 4.22 into seconds >>> 240 + 22 = 262

Now we can divide the numbers.

623/262 = 2.37786259542

If we round up the speed then it is about 2.4 m/s.
