Round all answers to 1 decimal place.
A. Find the speed (in m/s) in each of the following, given the distance and the time.
|
1) D = 10 m, t = 1 s |
2) D = 10 m, t = 2 s |
|
3) D = 10 m, t = 10s |
4) D = 10 m, t = 5s |
|
5) D = 1 km, t = 20 s |
6) D = 3 km, t = 40 s |
|
7) D = 40 km, t = 150 s |
8) D = 4.7 km, t = 3.8s |
|
9) D = 400 km, t = 4 hrs. |
10) D = 37 km, t = 15 min. |
|
11) D = 3000 km, t = 9.8 hrs |
12) D= 300 000 000 m, t = 1 s |
B. Find the distances in metres, given the speed and time.
|
1) s = 12 m/s, t = 15 s |
2) s = 1.7 m/s, t = 49.5 s |
