Answer 1

$\displaystyle\huge\red{\underline{\underline{Solution}}}$

FORMULA TO BE IMPLEMENTED

The speed of a body is defined as :

$\displaystyle \: \sf{ \: Speed = \: \frac{Distance \: Covered }{Time \: Taken} }$

GIVEN

A cyclist covers 950m in 5 minutes

TO DETERMINE

The of the cyclist in km/hour

CALCULATION

The total distance covered by the cyclist

$= \: 950 \: metre$

$= 0.95 \: \: km$

Total time taken

$= 5 \: \: minutes$

$= \displaystyle \: \frac{5}{60} \: \: hour$

$= \displaystyle \: \frac{1}{12} \: \: hour$

So the speed of the cyclist

$\displaystyle \: \sf{ \: = \: \frac{Distance \: Covered }{Time \: Taken} }$

$\displaystyle \: \sf{ \: = \: \frac{0.95 }{ \frac{1}{12} } } \: \: km/ hour$

$\displaystyle \: \sf{ \: = \: (0.95 \times 12) } \: \: km/ hour$

$\displaystyle \: \sf{ \: = \: 11.4 } \: \: km/ hour$

Answer 2

ANSWER:

D=950m=0.95

T=5/60=1/12.

S=D/T.

D=11.4m.
