How far did a frog jump if he travels at a rate of 2.1 m/s for 10 seconds?
1 answer:
Answer:
21 m
Explanation:
The motion of the frog is a uniform motion (constant speed), therefore we can find the distance travelled by using
where
d is the distance covered
v is the speed
t is the time
The frog in this problem has a speed of
v = 2.1 m/s
and therefore, after t = 10 s, the distance it covered is

1.6km = 1 mike? Wow that guy is tall.
I think you meant 1.6 km = 1 mile? Okay then if we're going 12 meters per second how much would you travel in one hour? First we need to figure out how many seconds are in an hour. There are 60 seconds in a minute and 60 minutes in an hour so:
60×60=3600 seconds in an hour
Now we will multiply that by 12 meters per second and we get:
And 43200 meters is 43.2 km (1000 meters in 1 kilometer) meaning 43.2 kilometers an hour. Since there are 1.6 km in one mile we must divide 43.2km to 1.6.
And so your speed is 27 miles per hour.
