$\begin{gathered}\boxed{\begin{array}{c|c|c|c}\bf No. & \bf Speed & \bf Time & \bf Distance \\ \\ \frac{\qquad\qquad}{} & \frac{\qquad\qquad}{} & \frac{\qquad\qquad}{} & \frac{\qquad\qquad}{} \\ \sf 1. & \sf 75km/h & \sf 3\frac{1}{2} h & \sf \frac{\qquad\qquad}{} \\ \\ \sf 2. & \sf \frac{\qquad\qquad}{} & \sf 20sec & \sf 200m \\ \\ \sf 3. & \sf 65km/h & \sf \frac{\qquad\qquad}{} & \sf 390km \\ \\ \sf 4. & \sf \frac{\qquad\qquad}{} & \sf 5.5h & \sf 473km \\ \\ \sf 5. & \sf 9.3m/s & \sf 86sec & \sf \frac{\qquad\qquad}{} \\ \\ \end{array}} \\ \end{gathered}$

$\boxed{\tt \red{speed = \frac{distance}{time} } }$

Case:1

• Speed=75km/h
• Time = 3½h = 3.5h

s=d/t

75=d/3.5

d=75×3.5

d=262.5km

d=262.5km

Case:2

• Time=20s
• Distance=200m

s=d/t

s=200/20

s=10m/s

s=10m/s

Case:3

• Speed=65km/h
• Distance=390km

s=d/t

65=390/t

t=390/65

t=6h

t=6h

Case:4

• Time= 5.5 h
• Distance=473 km

s=d/t

s=473/5.5

s=4730/55

s=86km/h

s=86km/h

Case:5

• Speed=9.3 m/s
• Time= 86 sec

s=d/t

9.3=d/86

d=86×9.3

d=799.8m

d=799.8m

$\begin{gathered}\boxed{\begin{array}{c|c|c|c}\bf No. & \bf Speed & \bf Time & \bf Distance \\ \\ \frac{\qquad\qquad}{} & \frac{\qquad\qquad}{} & \frac{\qquad\qquad}{} & \frac{\qquad\qquad}{} \\ \sf 1. & \sf 75km/h & \sf 3\frac{1}{2} h & \sf 262.5km \\ \\ \sf 2. & \sf 10m/s & \sf 20sec & \sf 200m \\ \\ \sf 3. & \sf 65km/h & \sf 6h & \sf 390km \\ \\ \sf 4. & \sf 86km/h & \sf 5.5h & \sf 473km \\ \\ \sf 5. & \sf 9.3m/s & \sf 86sec & \sf 799.8m \\ \\ \end{array}} \\ \end{gathered}$
