Question

ava runs 3.4 meters per second for 1/2 hour then walks 1.6 meters per second for 1/2 hour what is the total meters

Answer 1

9000m

Explanation:

Speed is distance divided by time taken:

Speed =
`(distance)/(time)`

Distance = speed x time

Total distance = distance 1 + distance 2

Note:

1hr = 3600s

0.5hr = 0.5 x 3600 = 1800s

Total distance = (3.4 x 1800) + (1.6 x 1800)

Total distance = 9000m
