You just have to find the lcm or least common factors of the denominators which is 60.
<span>Given:
s=4m/s
t=2m
d=?
Convert
1min=60sec
2 min x 60 sec / 1min = 120 sec
d=vt
= 4m/s * 120s
= 480 m
Example:
The given terms here are: Distance = 150 km Time = 7200 s Speed =? To express the speed in appropriate units, in this given we can simply kilometer to meter which is the SI unit for distance. Hence, we do the conversion first. </span><span><span>
1. </span>Conversion</span><span> 150 km = m? 1 km = 1000 m 150 km x 1000 m / 1 km = 150, 000 m </span><span><span>
2. </span>To find speed, we drive the formula d = vt where v = velocity or speed to v= d/t</span>
<span>V = d / t </span>
<span>V = 150, 000m / 7200 s </span>
<span>V = 20.83 m/s </span>
Hence, 20. 83 m/s is the speed.<span>

Answer:
x = 710
Step-by-step explanation:
1. Divide both sides by 2 to get x by itself
1420 = 2x
↓
1420 ÷ 2 = 2x ÷ 2
↓
710 = x
2. Switch sides
710 = x
↓
x = 710
I know it is not one of your options but that is the answer to 1420 = 2x
5
x 5
5
x 5
5³ x 5
They all work because their exponents all add up to 11.
Hope this helps!
